| Abstract: | We discuss the discontinuous mixed boundary value problem for nonlinear uniformly elliptic complex equation of second order in multiply connected domains. We first propose the boundary value problem and its new modified well-posedness. Under certain conditions, the solvability results for the above boundary value problem can be obtained, in which we use the estimates of solutions of the modified problem and the fixed-point theorem. The above problem possesses many applications in mechanics and physics etc. |
