Internally Calabi-Yau algebras.
I will explain what an internally Calabi-Yau algebra is, how such
algebras arise from Frobenius categories with cluster-tilting objects, and
vice versa. Frozen Jacobian algebras provide a source of internally
3-Calabi-Yau algebras, which are related to the categorification of cluster
algebras. I will show how to associate an internally 3-Calabi-Yau frozen
Jacobian algebra to any suitably graded quiver with potential.
