Second order casimirs for the affine Krichever--Novikov algebras ${\widehat{\mathfrak{gl}}}_{g,2}$ and ${\widehat{\mathfrak{sl}}}_{g,2}$

O. K. Sheinman

The second order casimirs for the affine Krichever--Novikov algebras ${\widehat{\mathfrak{gl}}}_{g,2}$ and ${\widehat{\mathfrak{sl}}}_{g,2}$ are described. More general operators which we call…
