One class of generalized boundary value problem for analytic functions

In this paper, a boundary value problem for analytic functions with two unknown functions on two parallel straight lines is studied, the general solutions in the different domains as well as the conditions of solvability are obtained in class $\{1\}$ , and the behaviors of solutions are discussed at $z=\infty$ and in the different domains, respectively. Therefore, the classic Riemann boundary value problem is extended further.
