Method of nonorthogonal functions for nonideally conjugate elliptic problems with discontinuous coefficients

A method of nonorthogonal functions is developed to solve a class of nonideally conjugate elliptic problems. The notation of nonideal conjugation conditions is modified. It allowed us to improve the method and develop the universal algorithm using the principle of the calculated domain decomposition into nonoverlapping subdomains. Sewing of solutions in the subdomains is carried out without iterations. Mathematical support is developed to solve problems with concentrated sources. Test problems are solved.
