Abstract

We construct a semidiscrete Galerkin method for the time-fractional diffusion equation. We prove the weak convergence of the method in the case of the right-hand side from a negative space with respect to the space variable. The continuity of the solution with values in a space of square-integrable functions is proven.

Keywordsdiffusion equation, Galerkin method, weak convergence
