(= Monografias de matematica, Bd. 1). - Aus der Bibliothek des Schweizer Mathematikers Kurt Strebel. «Kurt Strebel (20. April 1921 in Wohlen - 26. Oktober 2013 in Zürich) war ein Schweizer Mathematiker, der sich mit Funktionentheorie befasste. Strebel wurde 1953 bei Rolf Nevanlinna an der Universität Zürich promoviert (Über das Kreisnormierungsproblem der konformen Abbildung). 1953 bis 1955 war er am Institute for Advanced Study und an der Stanford University. Er wurde 1955 Professor in Fribourg und 1963 der Nachfolger von Nevanlinna an der Universität Zürich, als dieser zurück nach Finnland ging. Er gründete mit dem Nevanlinna-Schüler und Professor Hans Künzi das Nevanlínna Colloquium in Zürich (später auch an anderen Orten), um die Kontakte mit dem ehemaligen Professor in Zürich Rolf Nevanlinna aufrechtzuerhalten. 1977 wurde er Mitglied der Finnischen Akademie der Wissenschaften. Er war Invited Speaker auf dem Internationalen Mathematikerkongress 1974 in Vancouver (On quadratic differentials and extremal quasiconformal mappings). Nach ihm benannt sind die Strebel-Differentiale in der Teichmüller-Theorie.» 1100 gr. Schlagworte: Mathematik Naturwissenschaft.…

First Separate Printing. I don't pretend to understand the following quotations, but they come from authoritative sources. Von Neumann "developed between 1927 [the paper offered here] and 1929 a new mathematical framework of the theory which subsequently proved to be the most suitable formalism of nonrelativistic quantum mechanics as we use it today [1966], as well as of its extensions, the relativistic quantum mechanics of particles and the quantum theory of fields" (Max Jammer, "The Conceptual Development of Quantum Mechanics", pp. 314-315. "Von Neumann's most famous work in theoretical physics is his axiomatization of quantum mechanics. When he began work in that field in 1927 [in the paper offered here], the methods used by its founders were hard to formulate in precise mathematical terms: 'operators' on 'functions' were handled without much consideration of their domain of definition or their topological properties and it was blithely assumed that such 'operators,' when self-adjoint, could always be 'diagonalized' (as in the finite dimensional case), at the expense of introducing 'Dirac functions' as 'eigenvectors'. Von Neumann showed that mathematical rigor could be restored by taking as basic axioms the assumptions that the states of a physical system were points of a Hilbert space and that the measurable quantities were Hermitian (generally unbounded) operators densely defined in that space. This formalism, the practical use of which became available after von Neumann had developed the spectral theory of unbounded Hermitian operators (1929), has survived subsequent developments of quantum mechanics and is still the basis of non relativistic quantum theory; with the introduction of the theory of distributions, it has even become possible to interpret its results in a way similar to Dirac's original intuition" (J. Dieudonné, in Dictionary of Scientific Biography 14: 91).…

John von Neumann's first publication on quantum mechanics. Quoting the second paragraph of the paper: "The present paper has emerged from a lecture, given by D. Hilbert in the Winter Semester 1926/27 on the recent development of quantum mechanics, and it was prepared with the more essential help of L. Nordheim. Important parts of the mathematical execution originate from J. v. Neumann. The final write-up of this paper was provided by L. Nordheim. We believe that the Nordheim formulation of Jordan's and Dirac's ideas, which we have worked out here, have become substantially simpler and therefore more transparent and more easily understandable" (Chris Mitsch's English translation in 2019). "It was most fortunate for the development of our theory that Heisenberg's appeal to pure mathematicians was answered, at the right moment, in Göttingen by Hilbert himself. Since he had been consulted on numerous mathematical aspects of the theory ever since its inception, quantum mechanics was no terra incognita to him. In the fall of 1926 he began a systematic study of its mathematical foundations. Hilbert s approach was, of course, that of a pure mathematician. In his quest for logical rigor he elaborated Jordan's semi-axiomatic theory, based as it was on the notion of probability amplitudes. He first investigated the physical requirements which these amplitudes have to satisfy so as to lead to results in agreement with experience, and then searched for an analytical apparatus in terms of which these requirements could be formulated and satisfied. . . . Although Hilbert's contention concerning the finality of the analytical apparatus . . . was soon to be disproved, his conception of a separate analytical apparatus through the interpretation of which empirical relations can be brought into the form of mathematical statements became a basic element of the methodology of modern theoretical physics" (Jammer, "Conceptual Development of Quantum Mechanics", pp. 309-310).

"In his earliest work with operators . . ., von Neumann recognized the need for a detailed study of families of operators. Many of the subtler properties of an operator are to be found only in the internal algebraic structure of the algebra of polynomials in the operator (and its closures relative to various operator topologies) or in the action of this algebra on the underlying Hubert space. His interest in ergodic theory, group representations, and quantum mechanics contributed significantly to von Neumann's realization that a theory of operator algebras was the next important stage in the development of this area of mathematics. The dictates of the subject itself had called for this development. In [the [paper offered here], von Neumann initiated the study of the so-called 'rings of operators' also called 'W*-algebras ' and, most recently, 'von Neumann algebras' (by Dixmier). The latter term seems particularly apt. . ." (Richard V. Kadison, "Theory of Operators, Part II. Operator Algebras", Bulletin of the American Mathematical Society, Vol. 64, no. 3, part 2, May 1958, p. 61).…

An article discussing infinite tensor products of Hilbert spaces and the algebras acting on them. Arthur S. Wightman's copy with his ownership signature ("A.S. Wightman") and his notations to the formulae on four pages. Wightman was one of the founders of the axiomatic approach to quantum field theory, and originated the set of Wightman axioms. His work, including such titles as *PCT, Spin and Statistics and All That*, frequently cites the work of von Neumann. Although we wouldn't claim to understand the writings of either mathematician, we know an important association when we see one.…
