The subject of the research: nonlinear boundary value problems, including inverse ones, with non-classical conjugation conditions, as mathematical models of the relevant processes that constitute the essence of the research object; development and improvement of finite element methods, perturbation theory, complex analysis, etc. for solving relevant problems. Purpose of the work: to build new and improve existing mathematical and computer models of physical and chemical processes in porous media with thin inclusions (geobarriers with the possibility of generalization for engineering structures) under the conditions of parameter identification. Research methods: methodological approaches to the derivation of conjugation conditions based on conservation laws, the finite element method, methods of conformal and quasi-conformal mappings. Also, The conducted research is based on the methods of mathematical physics, soil mechanics, underground hydromechanics, hydrodynamics and soil science.
