The weak maximizing property is not inherited by subspaces of the domain
Alessandro Costa, Vinícius Miranda, Geivison Ribeiro
We construct a separable reflexive Banach lattice and a closed sublattice such that every bounded linear operator from into is compact, whereas ther…
Optimality in a Multilinear Extension of Kwapień's Theorem
Luis Miguel Castaño Marín, Luis Miguel Castaño-Marín, Daniel Núñez-Alarcón +2
Bayart, Pellegrino, and Rueda obtained diagonal absolute summability exponents for continuous \(m\)-linear operators from \((\ell_1)^m\) into \(\ell_p\). Their optimality was known…
Weak minimizing property and reflexivity
Vladimir Kadets, Geivison Ribeiro
For an operator T from X to Y denote m(T) the infimum of on the unit sphere of X. A sequence in is said to be minimizing for T if tends to m…
On Sequences with at Most a Finite Number of Zero Coordinates
Diego Alves, Geivison Ribeiro
In this paper, we analyze the existence of algebraic and topological structures in the set of sequences that contain only a finite number of zero coordinates. Inspired by the work…
A Quest for Convergence: Exploring Series in Non-Linear Environments
Geivison Ribeiro
This note presents an extension of a result within the concept of [S]-lineability, originally developed in 2019 by L. Bernal-González, J.A. Conejero, M. Murillo-Arcila, and J.B. Se…
