Extension of the Virasoro and Neveu-Schwartz algebras and generalized Sturm-Liouville operators

P. Marcel, V. Ovsienko, C. Roger

We consider the universal central extension of the Lie algebra $\Vect (S^1)${\math \s} $C^{\infty} (S^{1})$ . The coadjoint representation of this Lie algebra has a natural geometric i…

Extensions and contractions of the Lie algebra of q-pseudodifferential symbols

Boris Khesin, Volodymyr Lyubashenko, Claude Roger

We construct cocycles on the Lie algebra of pseudo- and q-pseudodifferential symbols of one variable and on their close relatives: the sine-algebra and the Poisson algebra on two-t…
