Degenerate Cohomological Hall algebra and quantized Donaldson-Thomas invariants for m-loop quivers (1102.3978v1)
Published 19 Feb 2011 in math.RT and math.AG
Abstract: We derive a combinatorial formula for quantized Donaldson-Thomas invariants of the m-loop quiver. Our main tools are the combinatorics of noncommutative Hilbert schemes and a degenerate version of the Cohomological Hall algebra of this quiver.
