Moretó–Rizo character correspondence conjecture for subnormalisers

This conjecture proposes a character correspondence between a finite group and the subnormaliser of a -element, preserving the -parts of character degrees and the fields generated by the corresponding character values. The source presents it as a recent conjecture motivating the study, but provides no resolution status.
