Bombal Gordón, Fernando ; Fernández Unzueta, M. ; Villanueva, Ignacio | Sociedad Matemática Mexicana | 2004We use well known properties of the tensor product of l(p)-spaces to study the local structure of projective and injective tensor products of Banach spaces. In particular we give a simple proof of the fact that the injective (resp. projective) t[...]texto impreso
Bombal Gordón, Fernando ; Fernández Unzueta, M. | Real Academia de Ciencias Exactas, Físicas y Naturales | 2000-01-01Let E be a (complex) Banach space and n be a positive integer, and denote by P( n E) the space of all n -homogeneous polynomials on E . The authors say that E has the m -FJ property (m -Farmer-Johnson property) if, whenever (x n ) n is a s[...]texto impreso
We study some classes of distinguished subsets of a Banach space in terms of polynomials and their relationship. This allows us to develop a systematic approach to study polynomial properties on a Banach space. We apply this approach to obtain s[...]texto impreso
Villanueva, Ignacio ; Bombal Gordón, Fernando ; Fernández Unzueta, M. | Polish Acad Sciencies Inst Mathematics | 2001The authors obtain in this paper a classification of projective tensor products of C(K) spaces, in terms of the behaviour of certain classes of multilinear operators on the product of the spaces, or the verification of certain Banach space prope[...]texto impreso
T Tauri stars (TTS) are low-mass pre-main-sequence stars that are accreting mass from the surrounding disc. The hotspots detected in some of them are probably heated by the release of gravitational energy in the accretion of the disc material on[...]texto impreso
We introduce a notion of unconditionally converging multilinear operator which allows to extend many of the results of the linear case to the multilinear case. We prove several characterizations of these multilinear operators (one of which seems[...]
