“An excellent collection of problems and their solutions with elements of theory to accompany the university course on mathematical methods of physics. It covers a broad variety of topics ranging from linear operators, differential and integral equations, special functions, and Green functions to group theory and their applications in physics. The book is recommended to students, PhD students, researchers, and teachers.”Prof. Boris KonopelchenkoUniversity of Salento, Italy
