This book studies the construction methods for solving one-dimensional and multidimensional inverse dynamical problems for hyperbolic equations with memory. The theorems of uniqueness, stability and existence of solutions of these inverse problems are obtained. This book discusses the processes, by using generalized solutions, the spread of elastic or electromagnetic waves arising from sources of the type of pulsed directional "impacts" or "explosions". This book presents new results in the study of local and global solvability of kernel determination problems for a half-space. It describes the problems of reconstructing the coefficients of differential equations and the convolution kernel of hyperbolic integro-differential equations by the method of Dirichlet-to-Neumann. The book will be useful for researchers and students specializing in the field of inverse problems of mathematical physics.

About the author
Durdimurod K. Durdiev is the Head of the Institute of Mathematics (named after V.I. Romanovsky) in the Academy of Sciences of the Republic of Uzbekistan, Bukhara State University, Uzbekistan. He is also Professor at the Department of Differential Equations, Bukhara State University, Uzbekistan. Professor Durdiev is graduated from Novosibirsk State University, Russia, in 1990. In 1992, at this university, he defended his Ph.D. thesis in physical and mathematical sciences. He defended his doctoral dissertation at the Institute of Mathematics and Information Technologies in Tashkent, in 2010. He teaches mathematical analysis, partial differential equations, calculus of variations and optimal control, theory of inverse problems of mathematical physics and theory of integral equations.
His areas of scientific interest are in inverse problems for equations of mathematical physics, kernel determination inverse problems in integro-differential equations of hyperbolic and parabolic types, direct and inverse problems for equations with fractional derivatives. Author of 5 books, more than 120 research papers in national and international journals of repute, he has supervised 9 Ph.D. theses during his career at the Institute of Mathematics and Bukhara State University. The main scientific research of Professor Durdiev is devoted to inverse problems, namely, the problems of determining the kernels that describe the viscous properties of the medium in integro-differential equations of hyperbolic and parabolic types with a convolution-type integral. This is a young trend in the theory of inverse problems that has emerged and rapidly developed over the past three decades.
