Abstract
In the paper, we study the problem of recovering the potential from the spectrum of the Dirichlet boundary value problem for a Sturm--Liouville equation with frozen argument on a closed set. We consider the case when the closed set consists of two segments and the frozen argument is at the end of the first segment. A uniqueness theorem and an algorithm solving the inverse problem are obtained along with necessary and sufficient conditions of its solvability. The considered case significantly differs from the one of the classical Sturm--Liouville operator with frozen argument.
