Title:Dimers, sandpiles and algebraic dynamics.

 

Abstract:

 

In this talk I will address the link between solvable models of
statistical mechanics and algebraic dynamical systems. The main reason
to believe in the existence of a strong link is the remarkable
coincidence of entropies of many celebrated solvable lattice models
(dimer matchings, domino tilings, spanning trees, etc) and entropies
of certain algebraic dynamical systems. Even though the question about
the existence of such a link was raised almost two decades ago, this
problem remained largely inaccessible. The development of the theory
of symbolic covers of algebraic dynamical systems has only recently
provided a suitable framework. I will describe in greater detail the
link between the solvable sandpile models and their algebraic
counterparts. The talk is based on a series of joint papers with D.
Lind (Seattle) and K. Schmidt (Vienna).
