Abstract
Let A be a finite dimensional algebra of finite global dimension over a finite field. In the present paper, we introduce certain elements in the Bridgeland Hall algebra of A, and give a multiplication formula for these elements. In particular, this generalizes the main result in Geng and Peng (2015, J. Algebra 437:116–132).
