Multiple almost summing operators
Joilson Ribeiro, Fabrício Santos
In this paper, we explore the concept of multilinear operators that are multiple almost summing and present a new concept of type and cotype of multilinear operators and investigat…
Transformations of sequence spaces by multipolinomials
Joilson Ribeiro, Fabrício Santos
In this paper we introduce a new approach to the concept of multipolynomials and generalize several results of the homogeneous polynomials and symmetric multilinear applications. W…
Coherence and compatibility: a stronger approach
Joilson Ribeiro, Fabrício Santos, Ewerton Torres
In this work we present a definition for coherence and compatibility of multilinear mappings and homogenous polynomial classes. These definitions are more restricted than the ones…
Absolutely - summing polynomials and the notion of coherence and compatibility
Joilson Ribeiro, Fabrício Santos
In this paper, we construct the abstract ideal of polynomials. We show this is an ideal of Banach and, in a second moment, we explore the question of the coherence and compatibilit…
