The Concept of a Riemann Surface The truth of Philidor's statementThis classic on the general history of functions was written by one of the twentieth century's best known mathematicians. Hermann Weyl, who worked with Einstein at Princeton, combined function theory and geometry in this high level landmark work, forming a new branch of mathematics and the basis of the modern approach to analysis, geometry, and topology. The author intended this book not only to develop the basic ideas of Riemann's theory of algebraic
