I implement state-of-the-art mathematical methods to engineering problems. Currently, I work on applications of the Difference Potential Method (DPM) that is a numerical method possessing many unique properties. In particular, it allows reducing the solution of a boundary-value problem in an arbitrary domain to the solution of a boundary equation without the knowledge of Green’s function. The main ingredient of the method, the difference potential, plays the role similar to that of the Cauchy-type integral in the theory of analytic functions.

 

I also work on the theory of boundary equations and the extension of Ryaben’kii’s potentials to continuous spaces:
