Derived invariance conjecture for reduced Drinfeld doubles

At least 19 years old · documented by

Let C1\mathcal{C}_1 and C2\mathcal{C}_2 be finitary hereditary connected Fq\mathbb{F}_q-linear categories. Their reduced Drinfeld doubles are denoted by D~HC1\widetilde{\mathbf{D}}\mathbf{H}_{\mathcal{C}_1} and D~HC2\widetilde{\mathbf{D}}\mathbf{H}_{\mathcal{C}_2}. Derived invariance conjecture. If C1\mathcal{C}_1 and C2\mathcal{C}_2 are derived equivalent, then

D~HC1≅D~HC2\widetilde{\mathbf{D}}\mathbf{H}_{\mathcal{C}_1}\cong\widetilde{\mathbf{D}}\mathbf{H}_{\mathcal{C}_2}

as algebras. This predicts that the reduced Drinfeld double is invariant under derived equivalence, with the stronger explicit functorial statement formulated in the following conjecture.
