Galkin V.A. is a specialist in the field of nonlinear equations of physical kinetics and hydrodynamics, the author of 141 scientific papers, including 3 monographs.
The main scientific results of V.A. Galkin: in the field of nonlinear equations, it is computational stability, global convergence of approximations for systems of conservation laws related to physical kinetics and gas dynamics. These studies turned out to be naturally related to the problems for nonlinear systems of conservation laws, including the equations of gas dynamics, hydrodynamics, Korteweg-de-Vries, Kadomtsev-Petviashvili, Maxwell-Vlasov-Liouville systems, etc. Fundamental results were obtained on finding out correctness classes, development and justification of global convergence of approximate methods for nonlinear conservation laws in the space of functional solutions, endowed with A.N. Tikhonov topology, introduced by V.A. Galkin. These results of V.A. Galkin have been widely discussed by the international scientific community over the past 30 years, they are recognized and constantly supported by grants from the RFBR, INTAS (000679), ISTC (2992, 2005).
