Cyclotomic character fields and sets of primes
Eugenio Giannelli, J. Miquel Martínez, Carolina Vallejo
Let where is an odd prime. Let be a finite group of order divisible by a prime . We show that the principal -block of contains a nontrivial i…
Alperin's bound and normal Sylow subgroups
Zhicheng Feng, J. Miquel Martínez, Damiano Rossi
Let be a finite group, a prime number and a Sylow -subgroup of . Recently, G. Malle, G. Navarro, and P. H. Tiep conjectured that the number of -Brauer characte…
Characters of prime power degree in principal blocks
J. Miquel Martínez
We describe finite groups whose principal block contains only characters of prime power degree.
Degree divisibility in Alperin-McKay correspondences
J. Miquel Martìnez, Damiano Rossi
Let p be a prime, B a p-block of a finite group G and b its Brauer correspondent. According to the Alperin-McKay Conjecture, there exists a bijection between the set of irreducible…
Character degrees in blocks and defect groups
Eugenio Giannelli, J. Miquel Martínez, A. A. Schaeffer Fry
A recent question of Gabriel Navarro asks whether it is true that the derived length of a defect group is less than or equal to the number of degrees of irreducible characters in a…
