Abstract: Let ${\cal A}$ be a finitary hereditary abelian category. We give a Hall algebra presentation of Kashaev's theorem on the relation between Drinfeld double and Heisenberg double. As applications, we obtain realizations of the Drinfeld double Hall algebra of ${\cal A}$ via its derived Hall algebra and Bridgeland's Hall algebra of $m$-cyclic complexes.
Keywords: Heisenberg double; Drinfeld double; derived Hall algebra; Bridgeland's Hall algebra
