The subject of the study is a nonlinear boundary value problems, including inverse ones, with nonclassical conjugation conditions, as mathematical models of the corresponding processes that make up the essence of the object of study; development and improvement of finite element methods, perturbation theory, complex analysis, etc., solving relevant problems. The purpose of the work is construction of new and improvement of existing mathematical and computer models of physicochemical controlled processes, including - in porous media with fine inclusions, under the conditions of parameter identification. Research Methods – mathematical and computer modeling, numerical methods of mathematical physics, computational experiment, physical and mechanical tests.
