Semi-Stable Chow-Hall Algebras of Quivers and Quantized Donaldson-Thomas Invariants
H. Franzen, M. Reineke
The semi-stable ChowHa of a quiver with stability is defined as an analog of the Cohomological Hall algebra of Kontsevich and Soibelman via convolution in equivariant Chow groups o…

Non-Schurian indecomposables via intersection theory
Hans Franzen, Thorsten Weist
For an acyclic quiver with three vertices, we consider the canonical decomposition of a non-Schurian root and associate certain representations of a generalized Kronecker quiver. T…

On the Semi-Stable CoHa and its Modules Arising from Smooth Models
Hans Franzen
We study a variant of the semi-stable Cohomological Hall algebra which we construct using equivariant Chow groups. This algebra, we call it the semi-stable ChowHa, arises as a quot…
