Homogeneously embedding stratified graphs in stratified graphs
Homogeneously embedding stratified graphs in stratified graphs
A 2-stratified graph $G$ is a graph whose vertex set has been partitioned into two subsets, called the strata or color classes of $G$. Two $2$-stratified graphs $G$ and $H$ are isomorphic if there exists a color-preserving isomorphism $\phi $ from $G$ to $H$. A $2$-stratified graph $G$ is said …
