Название: Applied Picard-Lefschetz Theory

Автор: Vassiliev V.A.

Аннотация:

Many classical partial differential equations in mathematical physics and other applied sciences have integral representations, i.e., are defined by integrals depending on parameters. This volume focuses on various versions of the Picard-Lefshetz theory and results that describe ramifications of four kinds of integral functions: volume functions, Newton-Coulomb potentials, fundamental solutions of hyperbolic partial differential equations, and multidimensional (Gelfand-Aomoto) hypergeometric functions. No information is provided on the author's affiliation, though 17 of his books on topology and related topics are listed among the 189 references.
