Measure and integral : new foundations after one hundred years
The present article aims to describe the main ideas and developments in the theory of measure and integral in the course and at the end of the first century of its existence
Central limit theorems for additive functionals of ergodic Markov diffusions processes
We revisit functional central limit theorems for additive functionals of
ergodic Markov diffusion processes. Translated in the language of partial
differential equations of evolution, they appear as diffusion limits in the
asymptotic analysis of Fokker-Planck type equations. We focus on the square
integrable framework, and we provide tractable conditions on the infinitesimal
generator, including degenerate or anomalously slow diffusions. We take
advantage on recent developments in the study of the trend to the equilibrium
of ergodic diffusions. We discuss examples and formulate open problems
SUSY Scaling Violations and UHECR
Advancing QCD toward astroparticle applications generates new challenges for
perturbation theory, such as the presence of large evolution scales with
sizeable scaling violations involving both the initial and the final state of a
collision. Possible applications in the context of Ultra High Energy Cosmic
Rays (UHECR) of these effects are discussed.Comment: 7 pages. 3 figures. Presented by C. Coriano at the Intl. Workshop

A COMMON FIXED POINT THEOREM Cheh-Chih
Many authors have defined contractive mappings on a complete metric space which are generalizations of the well-known Banach contraction, and which have the property that each such mapping has a unique fixed point. This contractive mapping principle has been one of the simplest and most useful tools in the study of nonlinear problems. During the past two decades, there has grown an extensive literature devoted to sharper forms of the contractive mapping principle. In one of the papers by Rhoades [5], 125 contractive definitions were listed; the most general fixed point theorems were stated, analysed and compared in it. Recently, Rhoades [6] proved the following interesting result: THEOREM A. Let X be a metric space with two metrics d and 6 satisfying the following conditions: (i) $(x,y) •< d(x,y) for each x,y in X, (ii) X is complete with respect to •, (iii) S,T: X •-X are continuous with respect to • and satisfying the followin
