Abstract
For a smooth surface , Porta-Sala defined a categorical Hall algebra generalizing previous work in K-theory of Zhao and Kapranov-Vasserot. We construct semi-orthogonal decompositions for categorical Hall algebras of points on . We refine these decompositions in K-theory for a topological K-theoretic Hall algebra.
