Inverse Problem for a Partial Differential Equation with Gerasimov–Caputo-Type Operator and Degeneration

In the three-dimensional open rectangular domain, problem of identification redefinition function for a partial differential equation with Gerasimov–Caputo-type fractional operator, degeneration, and integral form condition is considered in case 0<??1 order. A positive parameter present mixed derivatives. The solution this studied class regular functions. Fourier series method used, countable system ordinary equations degeneration obtained. presentation obtained using given additional condition. Using Cauchy–Schwarz inequality Bessel inequality, absolute uniform convergence proven.
