Description
Summary:In this paper, using the properties of generalized solutions in both the hyperbolic part and the elliptic part of a mixed domain, we study a boundary value problem with a conormal derivative for a mixed type equation of the second kind with Frankl-type conditions. The uniqueness of the solution to the problem under study is proven using the extremum principle, and its existence is proven by the method of integral equations. The theory of singular integral equations and Wiener–Hopf and Fredholm integral equations of the second kind are used to prove the existence of a solution to the problem.
