For a number of classes of hereditary distributed parameter systems, we prove a set of theoretical results concerning generalized solvability and convergence of Galerkin’s approximations.
We study elliptic, parabolic, and hyperbolic integro-differential equations, as well as equations with nonnegative-definite integral operators, including those of high order. We establish the existence and uniqueness of generalized solutions for initial-boundary value problems for those types of equations. The solvability theorems are proven by employing the a priori estimate method, which is modified according to the specific prorerties of integro-differential equations. The theorems that guarantee the existence of an optimal control (impulse, point, impulse-point etc) are derived directly from the corresponding solvability theorems. For the mentioned intergo-differential equations, as well as for the time-fractional diffusion equation, we obtain the theorems of convergence of the Galerkin approximations. The results obtained in the series of works can be used as theoretical foundations for investigation a broad class of physical, biological and other systems with memory, and also for the optimal control of such systems
