[HTML][HTML] Hyper-ideals of multilinear operators

G Botelho, ER Torres - Linear Algebra and its Applications, 2015 - Elsevier

Strongly -Lipschitz operators

A Bougoutaia, A Belacel, R Macedo - Advances in Operator Theory, 2023 - Springer
This work aims to define a new class of operators, called strongly p, σ-Lipschitz mappings.
