Quasi-compact Higgs bundles and Calogero-Sutherland systems with two types spins
S. Kharchev, A. Levin, M. Olshanetsky +1
We define the quasi-compact Higgs -bundles over singular curves introduced in our previous paper for the Lie group SL(). The quasi-compact structure means that th…

Calogero-Sutherland system with two types interacting spins
S. Kharchev, A. Levin, M. Olshanetsky +1
We consider the classical Calogero-Sutherland system with two types of interacting spin variables. It can be reduced to the standard Calogero-Sutherland system, when one of the spi…
