Conferencia Rex Dark. Using fields to construct finite p-groups

20 Jun 2022 | IUMPA seminar, News

I hope to describe how Galois fields can be used to construct: first Camina p-groups P (with [P, x] = P′ for every element x ∈ P − P′) [1]; then semidirect products of an extraspecial normal subgroup by a cyclic group [2]; and finally (in response to a question asked by D. MacHale, and prompted by an example due to R. Heffernan) finite soluble groups G with |Aut G| < |G|. \[x^2\]
