On rational definite summation

Sergey P. Tsarev

We present a partial proof of van Hoeij-Abramov conjecture about the algorithmic possibility of computation of finite sums of rational functions. The theoretical results proved in…

On a class of three-dimensional integrable Lagrangians

E. V. Ferapontov, K. R. Khusnutdinova, S. P. Tsarev

We characterize non-degenerate Lagrangians of the form $\int f (u_{x}, u_{y}, u_{t}) d x d y d t$ such that the corresponding Euler-Lagrange equations $ (f_{u_x})_x+ (f_{u_y})_y+ (f_{u_t})…
