Title: Two sum rules for the thermal n-point functions

Abstract

In real-time, thermal field theory there are 2{sup n} different n-point functions, but there are two linear combinations that sum to zero. Simple proofs of the two sum rules are given. Each sum rule has two forms: one for the one-particle-reducible functions and one for the amputated functions.
