Abstract
In the paper we consider an initial boundary value problem for one-dimensional diffusion equation in the domain with moving unknown boundary. By transformation of variables the problem is reduced to a coefficient inverse problem for some parabolic equation. Existence and uniqueness of solution of this problem are established.
