Abstract
This study investigates an initial-boundary value problem for a bounded domain in thermal interaction with an external medium, incorporating memory effects through the Caputo time-fractional derivative. Heat transfer through the lateral surface is modeled as a negative heat source in the governing differential equation. An a priori estimate for the solution is established. The solution is derived by using an operational method based on the Laplace transform in time.
