A unified Pietsch domination theorem
Geraldo Botelho, Daniel Pellegrino, Pilar Rueda
In this paper we prove an abstract version of Pietsch's domination theorem which unify a number of known Pietsch-type domination theorems for classes of mappings that generalize th…
Summability of multilinear mappings: Littlewood, Orlicz and beyond
Oscar Blasco, Geraldo Botelho, Daniel Pellegrino +1
In this paper we prove a plenty of new results concerning summabililty properties of multilinear mappings between Banach spaces, such as an extension of Littlewood's 4/3 Theorem. A…
Bifurcations in a class of polycycles involving two saddle-nodes on a Mobius band
Claudio Pessoa, Jorge Sotomayor
In this paper we study the bifurcations of a class of polycycles, called lips, occurring in generic three-parameter smooth families of vector fields on a Möbius band. The lips cons…
On algebras admitting a complete set of near weights, evaluation codes and Goppa codes
Cicero Carvalho, Ercilio Silva
In 1998 Hoholdt, van Lint and Pellikaan introduced the concept of a ``weight function'' defined on a F_q-algebra and used it to construct linear codes, obtaining among them the alg…
Lineability of summing sets of homogeneous polynomials
G. Botelho, M. C. Matos, D. Pellegrino
Given a continuous -homogeneous polynomial between Banach spaces and , in this paper we investigate some properties concerning…
