Аннотация:We study how a boundary value problem with a nonlocal integral condition of thefirst kind for a mixed type equation with a singular coefficient in a rectangular domain dependson a numerical parameter occurring in the equation. A uniqueness criterion is established, andtheorems on the existence and stability of a solution of the problem are proved. The solution isconstructed in closed form, and the convergence of the series in the class of regular solutions isjustified.
