Introducing Formalism in Economics: The Growth Model of John von Neumann
No full textThe objective is to interpret John von Neumann's growth model as a decisive step of the forthcoming formalist revolution of the 1950s in economics. This model gave rise to an impressive variety of comments about its classical or neoclassical underpinnings. We go beyond this traditional criterion and interpret rather this model as the manifestation of von Neumann's involvement in the formalist programme of mathematician David Hilbert. We discuss the impact of Kurt Gödel’s discoveries on this programme. We show that the growth model reflects the pragmatic turn of the formalist programme after Gödel and proposes the extension of modern axiomatisation to economics..Von Neumann, Growth model, Formalist revolution, Mathematical formalism, Axiomatics
Robert Neumann: Mit eigener Feder
No full textRobert Neumann (1897–1957, Austrian exiled author and Vicepresidet of the PEN International, was even a disputatious antifascist political writer. His essays, his letters and biograpical documents give a vivid portrait of the diversity of literary life in Germay and Austria (before 1933/after 1958) and of exile in England (1933–1958).Der österreichische Schriftsteller Robert Neumann (1897–1975), Exilant und Vizepräsident des PEN International, war auch ein streitbarer antifaschistischer Publizist. Seine politisch-literarischen Aufsätze, seine Briefe und biographischen Dokumente ergeben ein lebendiges und facettenreiches Bild des literarischen Lebens in Deutschland und Österreich (vor 1933/nach 1958) und des Exils in England (1933–1958)
Relative Haagerup property for arbitrary von Neumann algebras
No full textWe introduce the relative Haagerup approximation property for a unital, expected inclusion of arbitrary von Neumann algebras and show that if the smaller algebra is finite then the notion only depends on the inclusion itself, and not on the choice of the conditional expectation. Several variations of the definition are shown to be equivalent in this case, and in particular the approximating maps can be chosen to be unital and preserving the reference state. The concept is then applied to amalgamated free products of von Neumann algebras and used to deduce that the standard Haagerup property for a von Neumann algebra is stable under taking free products with amalgamation over finite-dimensional subalgebras. The general results are illustrated by examples coming from q-deformed Hecke-von Neumann algebras and von Neumann algebras of quantum orthogonal groups.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Analysi
A comparison of deflation and the balancing Neumann-Neumann preconditioner
No full textIn this paper we compare various preconditioners for the numerical solution of partial differential equations. We compare the well-known balancing Neumann Neumann preconditioner used in domain decomposition methods with a so-called deflation preconditioner. We prove that the effective condition number of the deflated preconditioned system is always, i.e. for all deflation vectors and all restrictions and prolongations, below the condition number of the system preconditioned by the balancing Neumann-Neumann preconditioner. Even more, we establish that both preconditioners lead to almost the same spectra. The zero eigenvalues of the deflation preconditioned system are replaced by eigenvalues which are one if the balancing Neumann-Neumann preconditioner is used. Moreover, we proved that the A-norm of the errors of the iterates build by the deflation preconditioner is always below the A-norm of the errors of the iterates build by the balancing Neumann-Neumann preconditioner. Additionally, the amount of work of one iteration of the de ation preconditioned system is less than the amount of work of one iteration of the balancing Neumann-Neumann preconditioned system. Finally, we establish that the deflation preconditioner and the balancing Neumann-Neumann preconditioner produces the same iterates if one uses certain starting vectors. Numerical results for porous media flows emphasize the theoretical results.Electrical Engineering, Mathematics and Computer Scienc
The Carnapian Aufbau model: epistemology of the sense-data
No full textThis paper proposes an interpretation theoretical model of the Aufbau of Rudolf Carnap, this interpretation contributes to upgrade the project original carnapian, in the sense of conferring to the constitutional program of construction logical, less committed analytic equipment with an ontology or clearly defined epistemology. The setting in phenomenal logical reconstruction practice is elaborated for the visual field as a model whose potential user is a fellow ideal percipient, and, a subject epistemic that operates in the same way that a scheduled computer when he has been given basic phenomenal information and some algorithms logical.Information, economy phenomenological, history, philosophy of science, structuralism program.
Relational implementation of simple parallel evolutionary algorithms
No full textRandomized search heuristics, among them evolutionary algorithms, are applied to problems whose structure is not well understood, as well as to hard problems in combinatorial optimization to get near-optimal solutions. We present a new approach implementing simple parallel evolutionary algorithms by relational methods. Populations are represented as relations which are implicitly encoded by (reduced, ordered) binary decision diagrams. Thereby, the creation and evaluation is done in parallel, which increases efficiency considerably.Britta Kehden, Frank Neumann, and Rudolf Berghamme

Eidos : Rudolf Borchardt zwischen Benedetto Croce und Aby Warburg
No full textWährend in der bisherigen Rezeption immer die Isolation des Dichters, Übersetzers, Essayisten und Redners Rudolf Borchardt (1877-1945) im literarischen Leben der Epoche hervorgehoben wurde, versuchen die in diesem Band versammelten Studien, den historischen Ort von Borchardts Gestalt und Werk im Zusammenhang von Poesie, Wissenschaft und Politik der ersten Jahrhunderthälfte zu bestimmen. Der Band zeigt, auf welch vielfältige Weise Borchardt mit zentralen Strömungen der Moderne verbunden war und wie intensiv der Austausch - in Anziehung wie Abstoßung - mit zahlreichen Künstlern, Wissenschaftlern und Politikern seiner Zeit gewesen ist. Die Rekonstruktion des Geflechts der historischen Bezüge, in dessen Zentrum Borchardt stand, ermöglicht eine differenzierte Beschreibung seiner poetischen Konzeptionen im Zusammenhang der literarischen Moderne, seiner wissenschaftlichen Entwürfe im wissenschaftsgeschichtlichen Kontext, seiner politischen Absichten und Irrtümer im politischen Kräftespiel der Epoche. Der Herausgeber ist Professor für Neuere deutsche Literatur an der Humboldt-Universität zu Berlin. 1989-1995 war er Präsident der Rudolf-Borchardt Gesellschaft
