In this post, we will see the book *A Collection of Problems on the Equations of Mathematical Physics* edited by V. S. Vladimirov. The contributors to the book include V .S. Vladimirov, V .P . Mikhailov, A. A. Vasharin, Kh. Kh.Karimova, Yu. V. Sidorov, and M.I. Shabunin. This is the associated problem book for Equations of Mathematical Physics and Partial Differential Equations which we have seen earlier.

**About the book**

The extensive application of modern mathematical techniques to

theoretical and mathematical physics requires a fresh approach to the course of equations of mathematical physics. This is especially true with regards to such a fundamental concept as the solution of a boundary value problem. The concept of a generalized solution considerably broadens the field of problems and enables solving from a unified position the most interesting problems that cannot be solved by applying classical methods. To this end two new courses have been written at the Department of Higher Mathematics at the Moscow Physics and Technology Institute, namely, “Equations of Mathematical Physics” by V.S. Vladimirov and “Partial Differential Equations” by V.P. Mikhailov (both books have been translated into English by Mir Publishers, the first in 1984 and the second

in 1978).The present collection of problems is based on these courses and

amplifies them considerably. Besides the classical boundary value problems, we have included a large number of boundary value problems that have only generalized solutions. Solution of these requires using the methods and results of various branches of modern analysis. For this reason we have included problems in Lebesgue integration, problems involving function spaces (especially spaces of generalized differentiable functions) and generalized functions (with Fourier and Laplace transforms), and integral equations.The book is aimed at undergraduate and graduate students in the physical sciences, engineering, and applied mathematics who have taken the typical “methods” course that includes vector analysis, elementary complex variables, and an introduction to Fourier series and boundary value problems. Asterisks denote the more difficult problems.

The book was translated from Russian by Eugene Yankovsky and was published in 1986.
