Abstract: The paper considers a parabolic equation with variable coefficients with a fractional derivative with respect to time, when a concentrated heat capacity of a certain value is placed on the boundary of the region. A priori estimates in the differential and difference interpretations are obtained. Numerical calculations using the sweep method are conducted.

Keywords: fractional order derivative, solution stability, prior estimate, stability of the difference scheme.
