In this, one of the first books to appear in English on the theory of numbers, the eminent mathematician Hermann Weyl explores fundamental concepts in arithmetic. The book begins with the definitions and properties of algebraic fields, which are relied upon throughout. The theory of divisibility is then discussed, from an axiomatic viewpoint, rather than by the use of ideals. There follows an introduction to p-adic numbers and their uses, which are so important in modern number theory, and the book culminates with an extensive examination of algebraic number fields.

Dieser Text ist die Transkription einer Vorlesung zur Funktionentheorie, die Hermann Weyl im Wintersemester 1910-11 an der Universitat Gottingen gehalten hat, kurz vor der Entstehung seines einflussreichen Buches uber Riemannsche Flachen, das auf der Fortsetzung dieser Vorlesung im Sommersemester 1911 beruht. Weyl betont in dieser Vorlesung die kinematische Deutung gebrochen-linearer Transformationen und die Beziehungen zwischen konformen Abbildungen und Stromungstheorie. Hohepunkt der Vorlesung ist der Vergleich der Riemannschen und Weierstrassschen Behandlung mehrdeutiger analytischer...

Nobel Laureate Simon Kuznets, famous as the founder of modern empirical economics, pioneered the quantitative study of the economic history of the Jews. Yet, until now, his most important work on the subject was unpublished. This second collection of previously unavailable material issued by Transaction brings to the public, for the first time, the most important economic work written on Jewish migration since that of Werner Sombart a century ago.

This volume of Kuznets' work includes three main essays. The first, titled "Immigration and the Foreign Born," was Kuznets' first work on...

When The New Democracy first appeared in 1912, it was widely regarded as one of the most influential works of the Progressive Era. Yet, despite continuing interest in the political thought of the Progressive Era, both Weyl and The New Democracy slipped into undeserved obscurity shortly after the author's death from cancer in 1919. Despite this, Weyl's book remains one of the most important links in the development of a liberal-progressive theory of democracy.

Weyl describes the efforts of a plutocracy seeking to control, often by corrupt means, the federal...
