      報告題目:Singularity categories, Hall algebras and i-quantum groups


      摘要:A quantum symmetric pair consists of a quantum group and its coideal subalgebra (called an i-quantum group). A quantum group can be viewed as an example of i-quantum groups associated to symmetric pairs of diagonal type. In this talk, we present a new Hall algebra construction of i-quantum groups. A new class of 1-Gorenstein algebras (called i-quiver algebras) arising from quivers with involutions is introduced, and their singularity categories are characterized by the existence of tilting objects. Their Ringel-Hall algebras are isomorphic to i-quantum groups. This is joint work with Weiqiang Wang (University of Virginia).
