Abstract:
The paper considers nonlocal boundary value problems for second-order elliptic equations, as well as local and nonlocal Riemann-Hilbert problems for analytic functions and their interrelation. Necessary and sufficient conditions for unique solvability are obtained and effective methods for solving the problems considered are indicated.
Keywords:Riemann-Hilbert problem, analytic function, elliptic equations, nonlocal boundary value problem
