Lectures on qualitative theory of differential equations

The book is written on the basis of lectures delivered at the Mechanics and Mathematics
Faculty of KazNU named after al-Farabi, as well as scientific works on the qualitative theory
of differential equations. It describes the solvability and construction of solutions of integral
equations, boundary-value problems of ordinary differential equations with phase and integral
constraints, and a constructive method for solving the boundary-value problem of a linear
integro-differential equation. The book is intended for undergraduates and doctoral students in
the specialty «Mathematics».
