Kaplan-Meier type survival curves for COVID-19: a health data based decision-making tool
J. M. Calabuig, L. M. García-Raffi, A. García-Valiente +1
Countries are recording health information on the global spread of COVID-19 using different methods, sometimes changing the rules after a few days. They are all publishing the numb…
A class of summing operators acting in spaces of operators
J. Rodríguez, E. A. Sánchez-Pérez
Let , and be Banach spaces and let be a subspace of , the Banach space of all operators from to . An operator is said to be…
Extension of Lipschitz-type operators on Banach function spaces
W. V. Cavalcante, P. Rueda, E. A. Sánchez-Pérez
We study extension theorems for Lipschitz-type operators acting on metric spaces and with values on spaces of integrable functions. Pointwise domination is not a natural feature of…
Local compactness in right bounded asymmetric normed spaces
Natalia Jonard-Pérez, Enrique A. Sánchez-Pérez
We characterize the finite dimensional asymmetric normed spaces which are right bounded and the relation of this property with the natural compactness properties of the unit ball,…
