Uncomplemented subspaces in operator and polynomial ideals
Autor: Sergio A. Pérez, Geraldo Botelho, Vinícius V. Fávaro
Publikováno v: Revista Matemática Complutense. 35:851-869
Generalizing a number of known linear and nonlinear results, we establish conditions for the space of linear operators belonging to a given operator ideal not to be complemented in the space of bounded linear operators, and for the space of n-homogen

On the Schur, positive Schur and weak Dunford–Pettis properties in Fréchet lattices
Autor: José Lucas P. Luiz, Geraldo Botelho
Publikováno v: Annales Fennici Mathematici
We prove some general results on sequential convergence in Fréchet lattices that yield, as particular instances, the following results regarding a closed ideal \(I\) of a Banach lattice \(E\): (i) If two of the lattices \(E\), \(I\) and \(E/I\) have

The Polynomial Hyper-Borel Transform
Autor: Geraldo Botelho, Raquel Wood
Publikováno v: Bulletin of the Brazilian Mathematical Society, New Series. 53:523-539
This paper develops a technique to represent linear functionals on spaces of homogeneous polynomials between Banach spaces. This technique applies to cases that are not covered by the classical polynomial Borel transform. We provide applications to r

Factorization and coincidence theorems for generalized adjoints
Autor: Leodan A. Torres, Geraldo Botelho
Publikováno v: Linear and Multilinear Algebra. 70:899-908
As a consequence of a factorization theorem, we establish conditions on the Banach spaces E and F so that the k-adjoint of every linear operator/homogeneous polynomial from E to F belongs a given o...

Hyper-ideals of multilinear operators and two-sided polynomial ideals generated by sequence classes
Autor: Geraldo Botelho, Raquel Wood
In the nonlinear field of multilinear operators and homogeneous polynomials between Banach spaces, we develop a technique, based on the transformation of vector-valued sequences, to create new examples of hyper-ideals of multilinear operators, polyno
