Degenerate cohomological Hall algebra and quantized Donaldson-Thomas invariants for $m$-loop quivers.
Doc. Math., J. DMV 17, 1-22 (2012)
Summary: 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.
