Algorithmic problems in right-angled Artin groups: complexity and applications
In this paper we consider several classical and novel algorithmic problems
for right-angled Artin groups, some of which are closely related to graph
theoretic problems, and study their computational complexity. We study these
problems with a view towards applications to cryptography.Comment: 16 page
On the algorithmic complexity of decomposing graphs into regular/irregular structures
A locally irregular graph is a graph whose adjacent vertices have distinct
degrees, a regular graph is a graph where each vertex has the same degree and a
locally regular graph is a graph where for every two adjacent vertices u, v,
their degrees are equal. In this work, we study the set of all problems which
are related to decomposition of graphs into regular, locally regular and/or
locally irregular subgraphs and we present some polynomial time algorithms,
NP-completeness results, lower bounds and upper bounds for them. Among our
results, one of our lower bounds makes use of mutually orthogonal Latin squares
which is relatively novel.Comment: 31 pages, 8 figure
