报告题目：Blocks with a cyclic hyperfocal subgroup

报告人: 胡学琴 教授（华中师范大学）

摘要：In this talk, we will investigate blocks with a cyclic hyperfocal subgroup. Under the assumption that the quotient of the hyperfocal subgroup in the defect group is abelian, we show that there is an isotypy between the block and its Brauer correspondent in the normalizer of the defect group. As an application, we show some properties of irreducible ordinary characters of the hyperfocal subalgebra under the same assumption as before. This is a joint work with Yuanyang Zhou.
