The paper is devoted to the study of inverse problems of finding, together with a solution u(x, t) of the diffusion equationutu+[c(x,t)+aq0(x,t)]u=f(x,t), the parameter a characterizing absorption (c(x,t) and q0(x,t) are given functions). It is assumed that, on the function u(x,t), nonpercolation conditions and some special overdetermination conditions of integral form are imposed. We prove existence theorems for solutions (u(x,t),a) such that the function u(x, t) has all Sobolev generalized derivatives appearing in the equation and a is a nonnegative number. © 2019, Pleiades Publishing, Ltd.
