Victor Isakov

Victor Isakov (November 4, 1947 – May 14, 2021) was a mathematician working in the field of inverse problems for partial differential equations and related topics (potential theory, uniqueness of continuation and Carleman estimates, nonlinear functional analysis and calculus of variation). He was a distinguished professor in the Department of Mathematics and Statistics at Wichita State University.

His areas of professional interest included:

*Inverse problems of gravimetry (general uniqueness conditions and local solvability theorems) and related problems of imaging including prospecting active part of the brain and the source of noise of the aircraft from exterior measurements of electromagnetic and acoustical fields. *Inverse problems of conductivity (uniqueness of discontinuous conductivity and numerical methods) and their applications to medical imaging and nondestructive testing of materials for cracks and inclusions. *Inverse scattering problems (uniqueness and stability of penetrable and soft scatterers). *Finding constitutional laws from experimental data (reconstructing nonlinear partial differential equation from all or some boundary data). *Uniqueness of the continuation for hyperbolic equations and systems of mathematical physics. *The inverse option pricing problem.
