Morava, Jack An algebraic analog of the Virasoro group. (English) Zbl 1045.22022 Czech. J. Phys. 51, No. 12, 1395-1400 (2001). Summary: The group of diffeomorphisms of a circle is not an infinite-dimensional algebraic group, though in many ways it acts as if it were. Here we construct an algebraic model for this object, and discuss some of its representations, which appear in the Kontsevich-Witten theory of 2D topological gravity.
