Universal bounds for the potential energy of weighted spherical codes are obtained by linear programming. The universality is in the sense of Cohn-Kumar -- every attaining code is optimal with respect to a large class of potential functions (absolute

In this paper we study the integrability of the Sasano system of type $A^{(2)}_4$ from the point of view of the Hamiltonian dynamics. We prove rigorously that for these values of the parameters for which the Sasano system of type $A^{(2)}_4$ has a pa

In 2006 Y. Sasano constructed higher order Painlev\'{e} systems which admit affine Weyl group symmetry of type $D^{(1)}_l, l=4, 5, 6, \ldots$. Every such a system is a Hamiltonian one with a coupled Hamiltonian associated to the Painlev\'{e} V equati
