Numerical integration in the discontinuous Galerkin method for elliptic problems.
Various aspects of the use of numerical integration for the evaluation of integrals appearing in discontinuous Galerkin formulations of a linear elliptic (diffusion) problem are studied. Error estimates are given....

The commutativity of integrals of motion for quantum spin chains and elliptic functions identities
We prove the commutativity of the first two nontrivial integrals of motion for quantum spin chains with elliptic form of the exchange interaction. We also show their liner independence for the number of spins larger than 4. As a byp...

Towards the proof of complete integrability of quantum elliptic many-body systems with spin degrees of freedom
We consider the problem of finding integrals of motion for quantum elliptic Calogero-Moser systems with arbitrary number of particles extended by introducing spin-exchange interaction. By direct calculation, after making certain ans...
