Existence of $2$ -Factors in Tough Graphs without Forbidden Subgraphs

Elizabeth Grimm, Songling Shan, Anna Johnsen

For a given graph $R$ , a graph $G$ is $R$ -free if $G$ does not contain $R$ as an induced subgraph. It is known that every $2$ -tough graph with at least three vertices has a $2$ -fac…

Rings with an elementary abelian $p$ -group of units

Sunil K. Chebolu, Jeremy Corry, Elizabeth Grimm +1

What are all rings $R$ for which $R^{*}$ (the group of invertible elements of $R$ under multiplication) is an elementary abelian $p$ -group? We answer this question for finite-dimensi…

Hamiltonicity of 3-tough $(K_{2} \cup 3 K_{1})$ -free graphs

Andrew Hatfield, Elizabeth Grimm

Chvátal conjectured in 1973 the existence of some constant $t$ such that all $t$ -tough graphs with at least three vertices are hamiltonian. While the conjecture has been proven for…
