Query: The multiplication formulas of quantum cluster algebras   By applying the property of Ext-symmetry and the vector bundle structures of
certain fibres, we introduce the notion of weight function and prove the
multiplication formulas for weighted quantum cluster characters associated to
abelian categories with the property of Ext-symmetry and 2-Calabi-Yau
triangulated categories with cluster-tilting objects.
