investigated. The solution of the problem was found by Riemann’s method. Theorems on the existence and uniqueness of
the solution were proved.}, number={1}, journal={Ukrains’kyi Matematychnyi Zhurnal}, author={IsmoilovA. I. and MamanazarovA. O. and UrinovA. K.}, year={2017}, month={Jan.}, pages={52-70} }
