Approximation-solvability of Nonlinear Functional and Differential Equations - Wolodymyr V. Petryshyn - Bog

Presents a constructive theory of solvability on linear and non-linear abstract and differential equations involving: proper operator equations in separable Banach spaces, and treats the problem of existence of a solution for equations involving pseudo; proper and weakly; and, proper mappings, and illustrates their applications.
