报告摘要:

The influence of the sizes of conjugacy classes and character degrees on the group structure is investigated by many intensively. It has long been a well known open problem that if one can read off the solvability of a finite group in terms of the set of

the sizes of conjugacy classes or the set of irreducible character degrees. This is resolved recently. We will survey related progress.
