Mikhail Litsarev

Biography

Mikhail’s current research is devoted to application of low-rank approximations to the multidimensional integration and finite-difference schemes. It appears that for certain classes of functions this technique allows to decrease the dimensionality/complexity of the problem down to (almost) linear cost in flops and memory, giving a perspective to design new, fast and efficient algorithms in scientific computing.

Research Interest

Computational physics: ab initio calculations of atomic, molecular, and condensed matter structure. Numerical mathematics, low-rank approximations, multidimensional integrals.
