The book discusses major topics in complex analysis with applications to
number theory. This book is intended as a text for graduate students of
mathematics and undergraduate students of engineering, as well as to
researchers in complex analysis and number theory. This theory is a
prerequisite for the study of many areas of mathematics, including the
theory of several finitely and infinitely many complex variables,
hyperbolic geometry, two and three manifolds and number theory. In
additional to solved examples and problems, the book covers most of the
topics of current interest, such as Cauchy theorems, Picard's theorems,
Riemann-Zeta function, Dirichlet theorem, gamma function and harmonic
functions.
