Variational Entropic Optimal Transport
Roman Dyachenko, Nikita Gushchin, Kirill Sokolov +3
Entropic optimal transport (EOT) in continuous spaces with quadratic cost is a classical tool for solving the domain translation problem. In practice, recent approaches optimize a…

Mosaic-skeleton approximation is all you need for Smoluchowski equations
Roman R. Dyachenko, Sergey A. Matveev, Bulat I. Valiakhmetov
In this work we demonstrate a surprising way of exploitation of the mosaic--skeleton approximations for efficient numerical solving of aggregation equations with many applied kinet…

Finite Size Effects in Addition and Chipping Processes
Roman R. Dyachenko, Sergey A. Matveev, P. L. Krapivsky
We investigate analytically and numerically a system of clusters evolving via collisions with clusters of minimal mass (monomers). Each collision either leads to the addition of th…
