The aim of the research is to adapt modern methods for studying the regularity of solutions to a class of anisotropic elliptic equations in order to obtain continuity conditions for solutions in terms of the Wolff potential. The study also envisages the construction of constructive existence conditions and the development of algorithms for finding solutions to integro-differential boundary value problems that are not resolved with respect to the derivative. Research methods include the adapted Kilpeläinen–Malý iteration technique, the pseudoinversion apparatus (the Moore–Penrose pseudoinverse operator), methods for solving matrix equations, regularization methods for ill-posed boundary value problems, and the least squares method. The obtained results are of a fundamental nature and are aimed at the further development of modern analytical methods for nonlinear and integro-differential equations. Within the framework of the study, the Kilpeläinen–Malý iteration technique was adapted to establish continuity conditions for solutions of the anisotropic elliptic N-Laplacian; the corresponding conditions are formulated in terms of the Wolff potential. In addition, the analytical framework for integro-differential boundary value problems not resolved with respect to the derivative was further developed, in particular, conditions for their regularization were identified and constructive criteria for the existence of solutions were formulated.
