About the Inductive Conditions for Global/Local Conjectures: Origins, Motivation, Past and Future

In the last 15 years many global-local conjectures have been reduced to simple groups, more precisely the conjectures hold if all simple groups satisfy a strong version of that conjectures, the corresponding so-called inductive condition. This way the McKay conjecture on characters of odd degree was prove. I will try to explain the origin and the nature of the inductive conditions. At the end I sketch when those conditions could be

Sylow Normalizers and Galois Action on Characters

In 2004, G. Navarro proposed a refinement of the McKay conjecture: the actions of a particular group of Galois automorphisms on the two character sets involved in the McKay conjecture are permutation isomorphic. The Navarro conjecture implies that the local condition that a Sylow p-subgroup of a finite group G is self-normalizing can be characterized in terms of the character theory of G; an implication that has been recently verified for all primes p. In the same spirit, we restrict our attention to the character theory of the principal p-block of G and analyze how it is connected with the structure of the normalizer of P.
