The Toll Walk Transit Function of a Graph: Axiomatic Characterizations and First-Order Non-definability

Manoj Changat, Jeny Jacob, Lekshmi Kamal K. Sheela +1

A walk $W = w_{1} w_{2} \dots w_{k}$ , $k \geq 2$ , is called a toll walk if $w_{1} \neq = w_{k}$ and $w_{2}$ and $w_{k - 1}$ are the only neighbors of $w_{1}$ and $w_{k}$ , respectively, on $W$ in a graph $G$ …

Recognition of chordal graphs and cographs which are Cover-Incomparability graphs

Arun Anil, Manoj Changat

Cover-Incomparability graphs (C-I graphs) are an interesting class of graphs from posets. A C-I graph is a graph from a poset $P = (V, \leq)$ with vertex set $V$ , and the edge-set is t…
