Equations of mathematical physics. 2nd edition, corrected and supplemented. Korzyuk V.I.

The book presented to you, dear reader, discusses the main equations of mathematical physics and tasks for them. Methods of studying different boundary tasks for differential equations of mathematical physics are presented, much attention is paid to the issue of resolving and evidence of the correct setting of the tasks under consideration. Along with many classic methods, a new method of classical solution is proposed using the example of the first mixed problem for a one -dimensional wave equation, which is easily transferred to many other tasks. A method of proof of the existence and uniqueness of a strong solution of boundary problems based on energy inequalities, as well as other functional methods, has been proposed. For students of mathematical and physical and mathematical specialties of universities.
