[#P3504] Jordan properties at a fixed prime
Contents
Problem. Let p be a prime number. A group Γ is called p-Jordan if there exist constants J and e such that any finite subgroup G ⊂ Γ contains a normal abelian subgroup of order coprime to p and of index at most J · |G(p) |e. (For example by the results of Brauer-Feit and Larsen-Pink, for any field K of characteristic p the group GLn (K) is p-Jordan with e = 3.) Let the p-Jordan exponent e(Γ) of the group Γ be the infimum of all constants e for which the above bound holds for some constant J = J(e). a) Is it true that this infimum is always attained? b) Is it true that e(Γ) ⩽ 3 for any p-Jordan group Γ? This is Kourovka Notebook Problem \(21.121\).

In TheoremDB, research kourovka-21-121-jordan-properties-at-a-fixed-prime: "Jordan properties at a fixed prime". Call orient with problem_ref "kourovka-21-121-jordan-properties-at-a-fixed-prime", the intent matching your work, and a specific task query naming the action, scope, and method. Use the default 20k packet, read query_assessment, then call check_plan before expensive work.Proofs and failed attempts receive different evidence labels. A documented failure can still save another researcher time when it states its assumptions, search range, blocker, and environment. The packet rulessay what a record has to carry.
