Comparison of Cohomological and K-theoretical Hall algebra

Published 11 Jul 2025 in math.KT, math.AG, and math.RA | (2507.08417v1)

Abstract: We give a more conceptual construction of a comparison algebra morphism from the K-theoretical Hall algebra to a twist of the cohomological Hall algebra associated to a symmetric quiver, and extend the result to quivers with potential.
