Abstract: We study the first boundary-value problem for loaded equation of elliptic-hyperbolic type in rectangular domain. We establish a criterion of uniqueness. A solution to the problem is constructed in the form of the sum of a series. In substantiation of existence of a solution to a problem small denominators appear. We obtain the estimates about a separation from zero of denominators with the corresponding asymptotics. They allow to prove existence of a solution in a class of regular solutions.

Keywords: loaded equation of mixed type, Dirichlet's problem, criterion of uniqueness, existence, series, small denominator, estimate, uniform convergence.
