is the polynomial whose evaluations at positive integers <font color="#008000">$x$<font color="#000000"> count the number of proper <font color="#008000">$x$<font color="#000000">-colourings of <font color="#008000">$G$<font color="#000000">.

 This polynomial was introduced by Birkhoff in 1912 in an attempt to prove the famous Four Colour Theorem which stood as an unsolved problem for over a century. Since then, the chromatic polynomial has been extensively studied and it has become an important

 object in the study of combinatorics. In this talk, I will discuss several  problems on the chromatic polynomial and other related graph polynomials, and give an overview of some recent results.</font></p>
