[HTML][HTML] A fast isomorphism test for groups whose Lie algebra has genus 2

PA Brooksbank, J Maglione, JB Wilson - Journal of Algebra, 2017 - Elsevier
Motivated by the desire for better isomorphism tests for finite groups, we present a
polynomial-time algorithm for deciding isomorphism within a class of p-groups that is well …

Algorithms based on*-algebras, and their applications to isomorphism of polynomials with one secret, group isomorphism, and polynomial identity testing

G Ivanyos, Y Qiao - SIAM Journal on Computing, 2019 - SIAM
We consider two basic algorithmic problems concerning tuples of (skew-) symmetric
matrices. The first problem asks us to decide, given two tuples of (skew-) symmetric matrices …

From independent sets and vertex colorings to isotropic spaces and isotropic decompositions: Another bridge between graphs and alternating matrix spaces

X Bei, S Chen, J Guan, Y Qiao, X Sun - SIAM Journal on Computing, 2021 - SIAM
In the 1970s, Lovász built a bridge between graphs and alternating matrix spaces, in the
context of perfect matchings Proceedings of FCT, 1979, pp. 565--574. A similar connection …

Testing isomorphism of graded algebras

P Brooksbank, E O'Brien, J Wilson - Transactions of the American …, 2019 - ams.org
We present a new algorithm to decide isomorphism between finite graded algebras. For a
broad class of nilpotent Lie algebras, we demonstrate that it runs in time polynomial in the …

comprehensive theoretical solutions to the following closely related problems: 1) List a …

[PDF][PDF] Conjugacy in finite classical groups

G De Franceschi, MW Liebeck, EA O'Brien - arXiv preprint arXiv …, 2024 - arxiv.org
Let $ G $ be a classical group defined over a finite field. We consider the following
fundamental problems concerning conjugacy in $ G $: 1. List a representative for each …

Supervised classification of diseases based on an improved associative algorithm

R Jiménez-Cruz, JL Velázquez-Rodríguez… - Mathematics, 2021 - mdpi.com
The linear associator is a classic associative memory model. However, due to its low
performance, it is pertinent to note that very few linear associator applications have been …

From independent sets and vertex colorings to isotropic spaces and isotropic decompositions

In the 1970's, Lov\'asz built a bridge between graphs and alternating matrix spaces, in the
context of perfect matchings (FCT 1979). A similar connection between bipartite graphs and …
