The reduced p-section subnormalizer conjecture
Let be a finite group, let be a prime, let , and let . Let be a set of representatives for the conjugacy classes in the reduced -section of . The reduced -section subnormalizer conjecture. There exists a bijection
such that it preserves -parts of degrees, vanishing on every element of , fields of character values there, and the subsets of characters nonzero at each . This strengthens the subnormalizer conjecture by controlling a whole reduced -section; it is open in general.

Progress summary
No public proof, counterexample, or other progress has been found; the conjecture remains open.
The conjecture asks for a character correspondence between a finite group and the subnormalizer of an element that preserves several refined properties on its reduced -section. The catalogued source reports no resolution as of May 2026.
Current status (as of September 2026): The reduced -section subnormalizer conjecture remains open, with no recorded proof, counterexample, or substantive progress.
