AND GABRIEL NAGY Definition
A self-adjoint element in a finite AW*-factor is spectrally symmetric, if its spectral measure under the quasitrace is invariant under the change of variables t 7−→ −t. We show that if A is an AW*-factor of type II1, a self-djoint element in A, without full support, has quasitrace zero, if and only if it can be written as a sum of at most four commuting spectrally symmetric elements. Moreover, ...
متن کاملRamy H . Bishay The ‘ Mighty Mouse
Tissue rejection remains a major problem in organ transplantation. The use of experimental animal models continues to enhance our understanding of the rejection process and offers strategies for its prevention. The popular mouse model of heterotopic cardiac transplantation has been used for over three decades to help investigators understand the pathogenesis of graft rejection and in turn, how ...
متن کاملThe Erdös-Nagy theorem and its ramifications
Given a simple polygon in the plane, a ip is de ned as follows: consider the convex hull of the polygon. If there are no pockets do not perform a ip. If there are pockets then re ect one pocket across its line of support of the polygon to obtain a new simple polygon. In 1934 Paul Erd}os conjectured that every simple polygon will become convex after a nite number of ips. The result was rst prove...
متن کاملIntrinsic Irreversibility and Sz.-Nagy-Foiaş Dilation Theory
An exact theory of irreversibility was proposed by Misra, Prigogine and Courbage (MPC) based on a non-unitary similarity transformation Λ mapping reversible dynamics into irreversible ones. In this work a characterization of the irreversible dynamics induced by the MPC theory, the structure of the reversible evolutions admitting such type of change of representation and a prototype for the tran...
متن کاملLinearly Similar Szökefalvi-nagy–foiaş Model in a Domain
In this paper we construct a new linearly similar functional model for linear operators and study its elementary properties. This model generalizes the Sz.-Nagy–Foiaş model for C0·-contractions and also for C0·-dissipative operators. We shall not restrict ourselves to the disk or the half-plane: the model will be constructed in a fairly arbitrary domain. The reduction of an operator to an “almo...
