[en] Lie algebras ; Mathematical physics ; conformal field theory
[en] Classically, starting from the Witt and Virasoro
algebra important examples of
Lie superalgebras were constructed.
In this write-up of a talk presented at the
Bia\l owie\.za meetings we report on results on Lie superalgebras of
Krichever-Novikov type. These algebras are multi-point and higher genus equivalents
of the classical algebras.
he grading in the classical case is replaced by an almost-grading.
It is induced
by a splitting of the set of points, were poles are allowed, into
two disjoint subsets.
With respect to a fixed splitting,
or equivalently with respect to a fixed
almost-grading, it is shown
that there is up to rescaling and equivalence a unique
non-trivial central extension
of the Lie superalgebra of Krichever--Novikov type. It is given explicitly.
