    Analogie und mathematisches Denken.Eberhard Knobloch - 1989 - Berichte Zur Wissenschaftsgeschichte 12 (1):35-47.
    This article deals with six aspects of analogical thinking in mathematics: 1. Platonism and continuity principle or the “geometric voices of analogy” (as Kepler put it), 2. analogies and the surpassing of limits, 3. analogies and rule stretching, 4. analogies and concept stretching, 5. language and the art of inventing, 6. translation, or constructions instead of discovery. It takes especially into account the works of Kepler, Wallis, Leibniz, Euler, and Laplace who all underlined the importance of analogy in finding out (...)

    Isomorphisms and subjective colors.Gregory R. Lockhead & Scott A. Huettel - 1999 - Behavioral and Brain Sciences 22 (6):959-960.
    Palmer describes a “subjective barrier” that limits knowledge of others' experience. We discuss how this barrier extends to all knowledge, becoming less distinct as theoretical constructs are strengthened. We provide evidence for isomorphic experience, among individuals with similar physiologies, by showing that perceived relations between colors are as similar when viewing pigments as when viewing subjective colors caused by flickering bars.

    Order-isomorphic η 1 -orderings in Cohen extensions.Bob A. Dumas - 2009 - Annals of Pure and Applied Logic 158 (1-2):1-22.
    In this paper we prove that, in the Cohen extension of a model M of ZFC+CH containing a simplified -morass, η1-orderings without endpoints having cardinality of the continuum, and satisfying specified technical conditions, are order-isomorphic. Furthermore, any order-isomorphism in M between countable subsets of the η1-orderings can be extended to an order-isomorphism between the η1-orderings in the Cohen extension of M. We use the simplified -morass, and commutativity conditions with morass maps on terms in the forcing language, to extend countable (...)

    Computable isomorphisms, degree spectra of relations, and Scott families.Bakhadyr Khoussainov & Richard A. Shore - 1998 - Annals of Pure and Applied Logic 93 (1-3):153-193.
    The spectrum of a relation on a computable structure is the set of Turing degrees of the image of R under all isomorphisms between and any other computable structure . The relation is intrinsically computably enumerable if its image under all such isomorphisms is c.e. We prove that any computable partially ordered set is isomorphic to the spectrum of an intrinsically c.e. relation on a computable structure. Moreover, the isomorphism can be constructed in such a way that the image of (...)

    Isomorphic formulae in classical propositional logic.Kosta Došen & Zoran Petrić - 2012 - Mathematical Logic Quarterly 58 (1):5-17.
    Isomorphism between formulae is defined with respect to categories formalizing equality of deductions in classical propositional logic and in the multiplicative fragment of classical linear propositional logic caught by proof nets. This equality is motivated by generality of deductions. Characterizations are given for pairs of isomorphic formulae, which lead to decision procedures for this isomorphism.

    Hamel-isomorphic images of the unit ball.Jacek Cichoń & Przemysław Szczepaniak - 2010 - Mathematical Logic Quarterly 56 (6):625-630.
    In this article we consider linear isomorphisms over the field of rational numbers between the linear spaces ℝ2 and ℝ. We prove that if f is such an isomorphism, then the image by f of the unit disk is a strictly nonmeasurable subset of the real line, which has different properties than classical non-measurable subsets of reals. We shall also consider the question whether all images of bounded measurable subsets of the plane via a such mapping are non-measurable.

    In der modernen Physik spielen Symmetrien eine herausragende Rolle zur Identifikation und Klassifizierung der fundamentalen Theorien und Entitäten. Symmetrien dienen der Darstellung invarianter Strukturen, das geeignete mathematische Werkzeug hierfür ist die Gruppentheorie. Eine Struktur lässt sich als eine Menge von Relationen verstehen, die einer Menge von Objekten aufgeprägt sind. Strukturell charakterisierte Objekte sind daher wesentlich über ihre relationalen Eigenschaften charakterisiert. Sieht man die theoretischen Entitäten wissenschaftlicher Theorien vornehmlich in dieser strukturellen Weise an, vertritt man eine moderate Variante eines wissenschaftlichen (...)

    Computable Isomorphisms of Boolean Algebras with Operators.Bakhadyr Khoussainov & Tomasz Kowalski - 2012 - Studia Logica 100 (3):481-496.
    In this paper we investigate computable isomorphisms of Boolean algebras with operators (BAOs). We prove that there are examples of polymodal Boolean algebras with finitely many computable isomorphism types. We provide an example of a polymodal BAO such that it has exactly one computable isomorphism type but whose expansions by a constant have more than one computable isomorphism type. We also prove a general result showing that BAOs are complete with respect to the degree spectra of structures, computable dimensions, expansions (...)

    Isomorphisms and nonisomorphisms of graph models.Harold Schellinx - 1991 - Journal of Symbolic Logic 56 (1):227-249.
    In this paper the existence or nonexistence of isomorphic mappings between graph models for the untyped lambda calculus is studied. It is shown that Engeler's D A is completely determined, up to isomorphism, by the cardinality of its `atom-set' A. A similar characterization is given for a collection of graph models of the Pω-type; from this some propositions regarding automorphisms are obtained. Also we give an indication of the complexity of the first-order theory of graph models by showing that the (...)

    Grounding rules and (hyper-)isomorphic formulas.Francesca Poggiolesi - 2020 - Australasian Journal of Logic 17 (1):70-80.
    An oft-defended claim of a close relationship between Gentzen inference rules and the meaning of the connectives they introduce and eliminate has given rise to a whole domain called proof-theoretic semantics, see Schroeder- Heister (1991); Prawitz (2006). A branch of proof-theoretic semantics, mainly developed by Dosen (2019); Dosen and Petric (2011), isolates in a precise mathematical manner formulas (of a logic L) that have the same meaning. These isomorphic formulas are defined to be those that behave identically in inferences. The (...)

    Strukturen technologischen Wissens: analytische Studien zu einer Wissenschaftstheorie der Technik.Klaus Kornwachs - 2012 - Berlin: Edition Sigma.
    Die Wissenschaft hat - von der Wissenschaftstheorie des 20. Jahrhunderts gründlich untersucht - bestimmte Strukturen ihres Wissens, ihrer Methodik der Wissensgewinnung und Wissensabsicherung entwickelt, die sie von anderen Arten des Umgangs mit Wissen - z.B. der Alltagserfahrung - signifikant unterscheidet. Für die Technikwissenschaften haben solche wissenschaftstheoretischen Untersuchungen jedoch bisher kaum stattgefunden. Was etwa die analytische Wissenschaftstheorie für die Naturwissenschaften geleistet hat, steht daher für die Technikwissenschaften noch aus. Denn das technische Wissen unterscheidet sich vom wissenschaftlichen Wissen in seiner inneren (...)

    Theorie dialektischer Strukturen.Gregor Betz - 2010 - Klostermann.
    Wo Meinungen aufeinanderprallen, um Verständnis geworben und Überzeugungsarbeit geleistet wird, sind Begründungen nicht weit. Für jede Überzeugung gibt es immer ein, zwei Gründe, die mit Gegengründen konfrontiert und, im Gegenzug, mit weiteren Überlegungen verteidigt werden usw. usf. Schnell sind wir verwirrt und drohen, ohne uns der "Grammatikregeln" vernünftigen Argumentierens zu besinnen, nicht mehr durchzublicken. Die Theorie dialektischer Strukturen leistet einen Beitrag zur Grammatik vernünftigen Argumentierens. Sie stellt Begriffe und Verfahren bereit, um Fragen, die sich angesichts einer komplexen Argumentation stellen (...)

    Isomorphisms between HEO and HROE, ECF and ICFE.Marc Bezem - 1985 - Journal of Symbolic Logic 50 (2):359 - 371.
    In this paper it will be shown that HEO and HRO E are isomorphic with respect to extensional equality. This answers a question of Troelstra [T, 2.4.12, p. 128]. The main problem is to extend effective operations to a larger domain. This will be achieved by a modification of the proof of the continuity of effective operations. Following a suggestion of A.S. Troelstra, similar results were obtained for ECF(U) and ICF E (U), where U is any universe of functions closed (...)

    We show that if A and $\widehat{A}$ are automorphic via Φ then the structures $S_{R}(A)$ and $S_{R}(\widehat{A})$ are $\Delta_{3}^{0}-isomorphic$ via an isomorphism Ψ induced by Φ. Then we use this result to classify completely the orbits of hhsimple sets.

    Cartesian isomorphisms are symmetric monoidal: A justification of linear logic.Kosta Dosen & Zoran Petric - 1999 - Journal of Symbolic Logic 64 (1):227-242.
    It is proved that all the isomorphisms in the cartesian category freely generated by a set of objects (i.e., a graph without arrows) can be written in terms of arrows from the symmetric monoidal category freely generated by the same set of objects. This proof yields an algorithm for deciding whether an arrow in this free cartesian category is an isomorphism.

    Zeichenhorizonte: semiotische Strukturen in Husserls Phänomenologie der Wahrnehmung.Diego D’Angelo - 2019 - Cham: Springer.
    In diesem Band deckt Diego D'Angelo semiotische Strukturen in der Husserl’schen Phänomenologie der Wahrnehmung auf. Ist es der Phänomenologie darum zu tun, die Erfahrung von Dingen in unserer Umwelt zu beschreiben, so ist dabei der Begriff des Horizontes von zentraler Bedeutung: Was wir unmittelbar wahrnehmen, verweist immer schon auf anderes, was nur „mitgegeben“ ist. Wenn wir Dinge wahrnehmen, haben wir nur eine bestimmte Perspektive, d.h. wir sehen lediglich einen Aspekt. Aber wir nehmen immer ganze Gegenstände wahr (wir sehen Tische (...)

    On isomorphic formalisations.Routen Tom - 1996 - Artificial Intelligence and Law 4 (2):113-132.
    Previous research into the formalisation of statute law identified a number of uses of language which posed problems for formalisation. A previous paper argued that these uses establish the requirement that a formalisation be isomorphic, but noted that this has odd consequences. This paper expands on what these consequences are and argues that they undermine the very idea of formalisation. Therefore, the whole argument constitutes a reductio ad absurdum of the idea of formalising statute law. The paper provides reasons why (...)

    Degrees of orderings not isomorphic to recursive linear orderings.Carl G. Jockusch & Robert I. Soare - 1991 - Annals of Pure and Applied Logic 52 (1-2):39-64.
    It is shown that for every nonzero r.e. degree c there is a linear ordering of degree c which is not isomorphic to any recursive linear ordering. It follows that there is a linear ordering of low degree which is not isomorphic to any recursive linear ordering. It is shown further that there is a linear ordering L such that L is not isomorphic to any recursive linear ordering, and L together with its ‘infinitely far apart’ relation is of low (...)
