Oberseminar Algebra und Geometrie - Prof. Dr. Markus Reineke (Universität Wuppertal) q-hypergeometric functions, Euler products and
Cohomological Hall Algebras
Wednesday, 24.11.2010 14:15 im Raum N 3
In a recent preprint, M. Kontsevich and Y. Soibelman derive
Donaldson-Thomas type invariants from Euler product factorizations of
certain q-hypergeometric functions, and relate these to convolution
algebra structures in equivariant cohomology of representation spaces. In
the talk we discuss a relation to noncommutative Hilbert schemes and to
the combinatorics of partitions, and we derive an explicit formula for
certain quantized Donaldson-Thomas type invariants.
