An optimal chromatic bound for the class of ${P_{3} \cup 2 K_{1}, P_{3} \cup 2 K_{1}}$ -free graphs

Athmakoori Prashant, S. Francis Raj

In 1987, A. Gyárfás in his paper ``Problems from the world surrounding perfect graphs'' posed the problem of determining the smallest $χ$ -binding function for $\mathcal{G}(F,\overl…

Linear $χ$ -binding functions for ${P_{3} \cup P_{2}, g e m}$ -free graphs

Athmakoori Prashant, S. Francis Raj, M. Gokulnath

Finding families that admit a linear $χ$ -binding function is a problem that has interested researchers for a long time. Recently, the question of finding linear subfamilies of $2K_…

$χ$ -binding function for a superclass of $2 K_{2}$ -free graphs

Athmakoori Prashant, S. Francis Raj

The class of $2 K_{2}$ -free graphs has been well studied in various contexts in the past. In this paper, we study the chromatic number of ${b u tt er f l y, hamm er}$ -free graphs, a superc…

$χ$ -binding functions for some classes of $(P_{3} \cup P_{2})$ -free graphs

Athmakoori Prashant, P. Francis, S. Francis Raj

The class of $2 K_{2}$ -free graphs have been well studied in various contexts in the past. It is known that the class of ${2 K_{2}, 2 K_{1} + K_{p}}$ -free graphs and $\{2K_2,(K_1\cup K_2)+K_p\…

Chromatic bounds for the subclasses of $p K_{2}$ -free graphs

Athmakoori Prashant, S. Francis Raj, M. Gokulnath

The concept of $χ$ -binding functions for classes of free graphs has been extensively studied in the past. In this paper, we improve the existing $χ$ -binding function for $\{2K_2, K…
