A natural correspondence between quasiconcave functions and fuzzy norms
Javier Cabello Sánchez, Daniel Morales González
In this note we show that the usual notion of fuzzy norm defined on a linear space is equivalent to that of quasiconcave function, in the sense that every fuzzy norm $N:X\times\mat…
Linearity of isometries between convex Jordan curves
Javier Cabello Sánchez
In this paper, we show that the -differentiability of the norm of a two-dimensional normed space depends only on distances between points of the unit sphere in two different w…
A precision on the concept of strict convexity in non-Archimedean analysis
Javier Cabello Sánchez, José Navarro Garmendia
We prove that the only non-Archimedean strictly convex spaces are the zero space and the one-dimensional linear space over , with any of its trivial norm…
The Banach space of quasinorms on a finite-dimensional space
Javier Cabello Sánchez, Daniel Morales González
Our main result states that, given a finite-dimensional vector space , the pseudometric defined in the set of continuous quasinorms …
