Abstract :
[en] We explain how the recently again discussed $N$-point Witt, Virasoro, and affine Lie algebras are genus zero examples of the multi-point versions of Krichever--Novikov type algebras as introduced and studied by Schlichenmaier. Using this more general point of view, useful structural insights and an easier access to calculations can be obtained. As example, explicit expressions for the three-point situation are given. This is a write-up of a talk presented at the Bialowieza meeting in 2015. Details can be found in a recent manuscript by the author.
