Word-Representation of Melon Graphs

Khyodeno Mozhui, K. V. Krishna

The notion of word-representable graphs is a generalization of comparability graphs, in which graphs are represented by words. The complexity of word-representation of a word-repre…

Line Graphs of Non-Word-Representable Graphs are Not Always Non-Word-Representable

Khyodeno Mozhui, Tithi Dwary, K. V. Krishna

A graph is said to be word-representable if there exists a word over its vertex set such that any two vertices are adjacent if and only if they alternate in the word. If no such wo…

On the Conjecture of the Representation Number of Bipartite Graphs

Khyodeno Mozhui, K. V. Krishna

While the problem of determining the representation number of an arbitrary word-representable graph is NP-hard, this problem is open even for bipartite graphs. The representation n…

Characterization of Split Comparability Graphs

Tithi Dwary, Khyodeno Mozhui, K. V. Krishna

A split graph is a graph whose vertex set can be partitioned into a clique and an independent set. A split comparability graph is a split graph which is transitively orientable. In…

Representation Number of Word-Representable Split Graphs

Tithi Dwary, Khyodeno Mozhui, K. V. Krishna

A split graph is a graph whose vertex set can be partitioned into a clique and an independent set. The word-representability of split graphs was studied in a series of papers in th…

On the Permutation-Representation Number of Bipartite Graphs using Neighborhood Graphs

Khyodeno Mozhui, K. V. Krishna

The problems of determining the permutation-representation number (prn) and the representation number of bipartite graphs are open in the literature. Moreover, the decision problem…

Words for the Graphs with Permutation-Representation Number at most Three

Khyodeno Mozhui, K. V. Krishna

The graphs with permutation-representation number (\textit{prn}) at most two are known. While a characterization for the class of graphs with the \textit{prn} at most three is an o…

On the Representation Number of Bipartite Graphs

Khyodeno Mozhui, K. V. Krishna

A word-representable graph is a simple graph which can be represented by a word over the vertices of such that any two vertices are adjacent in if and only if they…
