Singularities of Analytic Functions
Edited by R. P. Boas

The first volume of Polya's papers deals with singular points of analytic functions and with other broadly related topics, such as conformal mappings, entire functions, and the rate of growth of analytic functions.

Location of Zeros
Edited by R. P. Boas

The papers in this volume cluster about the following topics: the location of the zeros of polynomials and other analytic functions; the approximation of analytic functions by polynomials in which the location of zero is restricted (these papers represent some of Polya's most influential work); the behavior of the zeros of successive derivatives; the zeros of functions defined by trigonometric integrals; and the signs of derivatives and their analytic character.The volume also includes a paper that is not about zeros but contains a representation theorem for positive polynomials in several
