Artin-Schreier towers of finite fields
Leandro Cagliero, Allen Herman, Fernando Szechtman
Given a prime number , we consider the tower of finite fields , where each step corresponds to an Artin-Schreier extension of degr…
Sums of binomial coefficients modulo and groups of exponent
Fernando Szechtman
We give a simple matrix-based proof of congruence equations modulo a prime involving sums of binomial coefficients appearing in Pascal's triangle. These equations can be used t…
Isomorphism of relative holomorphs and matrix similarity
Volker Gebhardt, Alberto J. Hernandez Alvarado, Fernando Szechtman
Let be a finite-dimensional vector space over the field with elements, where is a prime number. Given arbitrary , we consider the semidirect pr…
The automorphism group of finite -groups associated to the Macdonald group
Alexander Montoya Ocampo, Fernando Szechtman
Given positive integers and , where is assumed to be an odd prime, we determine the automorphism groups of -groups , , and of orders , , and…
The automorphism tower of the Mennicke group
Fernando Szechtman
We compute the automorphism tower of the centerless Mennicke group
