Compact weighted Frobenius-Perron operators and their spectra
In this note we characterize the compact weighted Frobenius-Perron operator $p$ on $L^1(Sigma)$ and determine their spectra. We also show that every weakly compact weighted Frobenius-Perron operator on $L^1(Sigma)$ is compact.
متن کاملDivorce risk factors and their variations over time in Spain
The aim of this article is to analyse the risk factors for marriage dissolution in Spain and their variations over time for women married between 1949 and 2006. The data are drawn from the Survey of Fertility, Family, and Values of 2006. The article analyses the transition from first marriage to marital dissolution for couples who married in two eras: the period prior to the enactment of the Di...
متن کاملPulsar spectra of radio emission
We have collected pulsar flux density observations and compiled spectra of 281 objects. The database of Lorimer et al. (1995) has been extended to frequencies higher than 1.4 GHz and lower than 300 MHz. Our results show that above 100 MHz the spectra of the majority of pulsars can be described by a simple power law with average value of spectral index < α >= −1.8 ± 0.2. A rigorous analysis of s...
متن کاملAnalysis of Source Spectra
The purpose of this paper is to present the fundamentally basic aspects of source spectra through the preliminary use of the one-dimensional Haskell source model which assumes a finite fault with a constant rupture velocity. Teleseismic distances are assumed, such that the far field term dominates, allowing the P and S waves emanating from the source to be effectively considered double couple p...
متن کاملVariations on Supersymmetry Breaking and Neutrino Spectra
The problem of generating light neutrinos within supersymmetric models is discussed. It is shown that the hierarchy of scales induced by supersymmetry breaking can give rise to suppression factors of the correct order of magnitude to produce experimentally allowed neutrino spectra. Talk presented by F. Borzumati at the Post Summer Institute Workshop on “Neutrino Physics” Fuji-Yoshida, Japan, Au...
