HOLOMORPHIC QUADRATIC DIFFERENTIALS ON GRAPHSAND THE CHROMATIC POLYNOMIAL II
(after RICHARD KENYON, WAI YEUNG LAM )

In the classical theory holomorphic quadratic differentials (HQD) on Riemann surfaces are connected to many important things: harmonic functions, dynamical systems, minimal surfaces and so on. There exists a discrete analogue on graphs which preserves such rich relations.
In this talk we will discuss some properties of HQD, which will allow us to evaluate chromatic polynomial of a graph at negative integer value.
