Connected graph sums under a stability condition
Series: Mathematical Physics and Probability Seminar

Presenter: William Faris, University of Arizona
Equilibrium statistical mechanics requires a bound on a sum indexed by connected graphs.The standard technique is to find the bound as a sum indexed by tree graphs. This talk presents a recent result of Ueltschi for the case when the potential energy has a negative part. The only requirement is a stability condition.
