(The analysis leading to these equat ions will be out l ined in Sect ion 2.) Here, a is a n u m b e r and g (x ) a funct ion def ined on some interval ; bo th a and g(x ) are to be de te rmined . W e… (More)

We say that a representation of an algebra, of local observables has short-range correlations if any observable which can be measured outside all bounded sets is a multiple of the identity, and that… (More)

I will discuss in this article some recent progress in the problem of proving existence and uniqueness of solutions to Newton's equations of motion for infinite systems of classical particles… (More)

It is proved for fermi systems that each translationally invariant state co with square integrable correlation functions approaches a limit under the free time evolution. The limit state is the gauge… (More)

The International Film Oroup has passed Its embryonic stage and is on the way to life. For that occasion, we want to give a sort of statement of policy. The prime aim of the group is to present films… (More)

We obtain a formula for the essential spectral radius ess of transfer-type operators associated with families of C 1+ diieomorphisms of the line and Zygmund, or HH older, weights acting on Banach… (More)
