Abstract:Existence of dynamics for infinitely many hard-spheres inv dimensions is proven in a set of full equilibrium measure.Singular unbounded perturbations are considered with pair potentials diverging as (x – a)lambda, lambda>2 anda is the hard-core diameter. Long range forces are allowed with potentials decreasing at infinity asx lambdaprime, lambdaprime <v. The result corrects and generalizes a proof given in a previous paper by the same authors.Research partially supported by a CNR fellowship Posit. 204530.Research partially supported by a CNR fellowship.
