A note on cluster expansions, tree graph identities, extra 1/N! factors!!! Academic Article uri icon


  • We draw attention to a new tree graph identity which substantially improves on the usual tree graph method of proving convergence of cluster expansions in statistical mechanics and quantum field theory. We can control expansions that could not be controlled before. © 1984 D. Reidel Publishing Company.
