Stable equivalence of Morita type and quotient fusion system
Conghui Li
In this note, we prove that stable equivalences of Morita type between blocks of finite groups induce identification of certain quotient fusion systems under sone assumption. We al…

Non-injective inductions and restrictions of modules over finite groups
Conghui Li, Yuting Tian
In this note, we extend the inductions and restrictions of modules over finite groups to non-injective group homomorphisms, establishing transitivity, Frobenius reciprocity, Mackey…

On stable equivalences of Morita type and nilpotent blocks
Conghui Li
In this note, we give a new proof by module-theoretic methods for a result of Puig asserting that blocks which are stable equivalent of Morita type to nilpotent blocks are also nil…
