Keep Nibbling at the Edges

Keep nibbling at the edges.

Alifelong passion for natural history and an aptitude for chemistry had led me to study for a B.Sc. in biochemistry at University College London (UCL) from 1963 to 1966. It was during this period that the allosteric theory of enzyme regulation was put forward by JacquesMonod, Jean-Pierre Changeux, and Francois Jacob at the Institute Pasteur. This explained how the end products of a biosynthetic...

Chromaticity of Turan Graphs with At Most Three Edges Deleted

Let $P(G,lambda)$ be the chromatic polynomial of a graph $G$. A graph $G$ ischromatically unique if for any graph $H$, $P(H, lambda) = P(G,lambda)$ implies $H$ is isomorphic to $G$. In this paper, we determine the chromaticity of all Tur'{a}n graphs with at most three edges deleted. As a by product, we found many families of chromatically unique graphs and chromatic equivalence classes of graph...
