From the book reviews: "The book is devoted to the study of nonlinear Volterra and Fredholm integral equations. This extremely clear, well-written and self-contained monograph offers to a wide class of readers a valuable theoretical foundation in the theory of nonlinear integral equations and their applications to nonlinear boundary value problems encountered in various fields of the physical, chemical, and biological sciences. ... Throughout the book many mathematical examples are included to illustrate the theory." (D. G. Natroshvili, Mathematical Reviews, June, 2014)
