‎Quantenmechanik und Gruppentheorie. - [EARLY ANALYSIS OF THE FOUNDATIONS OF QUANTUM MECHANICS]‎

‎Berlin, Julius Springer, 1927. 8vo. In contemporary half cloth with gilt lettering to spine. In ""Zeitschrift für Fhysik"", vol. 46. Entire volume offered. Library stamp to title page. Pp. 1-46. [Entire volume: VII, (1), 902 pp.].‎

‎First printing of Weyl's exceedingly important paper which initially did not attract much attention but ""its repercussion turned out to be remarkably strong in the long range"". (Scholz, Weyl Entering the ’New’ Quantum Mechanics Discourse , p. 14). In it Weyl put forth an analysis of the foundations of quantum mechanics.""Weyl's (1927) paper, referred to by Yang above, is entitled Quantenmechanik und Gruppentheorie (Quantum Mechanics and Group Theory). In it, Weyl provides an analysis of the foundations of quantum mechanics and he emphasizes the fundamental role Lie groups play in that theory. Weyl begins the paper by raising two questions: (1) how do I arrive at the self-adjoint operators, which represent a given quantity of a physical system whose constitution is known, and (2), what is the physical interpretation of these operators and which physical consequences can be derived from them? Weyl suggests that while the second question has been answered by von Neumann, the first question has not yet received a satisfactory answer, and Weyl proposes to provide one with the help of group theory."" (SEP)Weyl’s approach to quantization was so general that for decades to come it did not attract much attention of physicists. At the beginning it even attracted very few successor investigations inside mathematics and was not noticed in the foundation of QM discourse, which was exclusively shaped by the Hilbert and von Neumann view until the 1950s. Although the immediate reception of Weyl’s early contributions to QM until about 1927, in particular his (Weyl 1927), was very sparse, its repercussion turned out to be remarkably strong in the long range:""1. A first and immediate next step was made by Marshall Stone and John von Neumann. They both took up Weyl’s statement of a uniquely determined structure of irreducible unitary ray representations. The result of this work is (for finite n) the now famous Stone/von Neumann representation theorem.2. A second line of repercussions may be seen in that part of the work of E. Wigner and V. Bargmann, which dealt with unitary and semi-unitary ray representations. In particular Wigner’s now famous work (at the time among physicists completely neglected) on the irreducible unitary ray representations of the Poincar´e group (Wigner 1939) looks like a next step beyond Weyl’s non-relativistic quantum kinematics from 1927. 3. A third impact is clearly to be seen in George Mackeys’s work. Mackey expressedly took up Weyl’s perspective (Mackey 1949) and developed it into a broader program for the study of irreducible unitary representations of group extensions.4.Finally, Weyl quantization was taken up by mathematical physicists from the later 1960s onwards with the rise of deformation quantization (Pool 1966). Here the starting point was the idea to translate the operator product introduced by Weyl’s own quantization.The last two points lead straight into very recent developments of mathematical physics.""

‎Über die Konvergenz von Reihen, die nach Orthogonalfunktionen fortschreiten.‎

‎Leipzig, B.G. Teubner, 1909. 8vo. Original printed wrappers, no backstrip and a small nick to front wrapper. In ""Mathematische Annalen. Begründet durch Alfred Clebsch und Carl Neumann. 67 Band. 2. Heft."" Entire issue offered. Internally very fine and clean. [Weyl:] Pp. 225-45. [Entire issue: Pp. 145-280].‎

‎First printing of Weyl's paper on the convergence of series which continue as orthogonal functions. ""Very few of Weyl's 150 published books and papers-even those chiefly of an expository character-lack an original idea or afresh viewpoint. The influence of his works and of his teaching was considerable: he proved by his example that an ""abstract"" approach to mathematics is perfectly compatible with ""hard"" analysis and, in fact, can be one of the most powerful tools when properly applied.""

‎First printing of WEYL ambitious paper in which he used the Stoney units, named after the Irish physicist George Johnstone Stoney, to unify quantum processes and gravity thereby seeking to create a ""Unified Field Theory"". The paper appears to have inspired Dirac's fascination with the large number hypothesis.Also contain in this volume is the first appearance of EÖTVÖS' important paper in which he explains the eastward deflection of falling objects. In the paper, he also describes a device with which the effect can be demonstrated experimentally.The Eötvös effect is the change in perceived gravitational force caused by the change in centrifugal acceleration resulting from eastbound or westbound velocity. When moving eastbound, the object's angular velocity is increased (in addition to the earth's rotation), and thus the centrifugal force also increases, causing a perceived reduction in gravitational force. This phenomenon had been observed in the early 20th century on research ships on which gravity was measured" they noticed that measurements of g yielded smaller values when the ship went eastward, and larger ones when they went westward. These observations are mentioned by Eötvös in a paper in which he provides the explanation of the effect.‎

‎Scarce first edition. As privatdozent Hermann Weyl had given a course on Riemann's theory of functions" but instead of following his predecessors in their constant appeal to intuition for the definition and properties of Riemann surfaces, he set out to give to their theory the same kind of axiomatic and rigorous treatment that Hilbert had given to Euclidean geometry. Using Hilbert's idea of defining neighborhoods by a system of axioms, and influenced by Brouwer's clever application of Poincare's simplicial methods (which had just been published), he gave the first rigorous definition of a complex manifold of dimension 1 and a throughout treatment (without any appeal to intuition) of all the questions regarding orientation, homology, and fundamental groups of these manifolds. ""Die Idee der Riemannschen Fläche"" (1913) immediately became a classic and inspired all later developments of the theory of differential and complex manifolds.(J.Dieudonne in DSB).‎
