The purpose of this paper is to discuss the maximality as a discrete group of the group GZ of all rational integral matrices of the Real Special Orthogonal Group G = SO (H) for all unimodular integrral symmetric  n   by ...

We introduce matrix-valued weight functions of arbitrary size, which are analogues of the weight function for the Gegenbauer or ultraspherical polynomials for the parameter ν> 0. The LDU-decomposition of the weight is ...

Exploramos la clase de las ternas (M, ∇, P) en las cuales M es una variedad, r una conexión afín en M y P una G-estructura en M. Dentro de esta clase están las variedades infinitesimalmente homogéneas, que se caracterizan ...

Let I I be a symmetrically-normed ideal of the space of bounded operators acting on a Hilbert space H H . Let View the MathML source {pi}w1 (1≤w≤∞) (1≤w≤∞) be a family of mutually orthogonal projections on H H . The ...
