The Separable Quotient Problem and the Lotz Property in Banach Spaces
Gustavo Araújo, Anderson Barbosa, Juan B. Seoane-Sepúlveda
In this paper, in addition to establishing several new sufficient or equivalent conditions for the well-known Separable Quotient Problem (SQP), we show that every infinite-dimensio…
SOT-large subspaces of non-cyclic operators
N. G. Albuquerque, G. Araújo, L. Bernal-González +2
In this paper, we consider the strong operator topology (SOT) on the space of continuous linear operators on an infinite-dimensional Fréchet space . The existe…
A Levin-Milman theorem for Young variation
N. G. Albuquerque, D. Bugajewska, E. Demétrio +1
In 1940, Levin\footnotemark[1] and Milman proved that a closed linear subspace of whose elements all have bounded Jordan variation must be finite-dimensional. We prove its…
Algebrability and Riemann integrability of the composite function
E. D'Aniello, J. Fernández-Sánchez, M. Maiuriello +1
In this note we show that there exist a -generated free algebra of Riemann integrable functions and a free algebra $\mat…
The interplay between recurrence and hypercyclicity in dissipative contexts
E. D'Aniello, M. Maiuriello, J. B. Seoane Sepulveda
Motivated by recent investigations \cite{Costakis, Bonilla} on the notion of recurrence in linear dynamics, we deepen into the notions of recurrence and frequent recurrence in the…
A simple unified explanation of several genetic issues on today's human population and on archaic humans
Per H. Enflo, Gustavo A. Muñoz-Fernández, Juan B. Seoane-Sepúlveda
We will give a simple, unified, possible explanation of several debated genetic issues on today's humans, Neandertals and Denisovans. In particular it is shown by means of a simple…
