π-块的剩余集

摘要

In this paper we discuss the relationship between the greatest common divisor ofrnthe degrees of irreducible characters and that of the principal indecomposable characters in a r-rnblock, then give an equivalent statement of Harada Conjecture in the form of the π-blockrntheory.%本文讨论了π-块中不可约特征标度数的最大公因子与主不可分解特征标度数的最大公因子之间的关系,给出了π-块形式的Harada猜想的等价条件.
