Plasticity in graph metric spaces and their hyperspaces
Clayton Suguio Hida
A metric space is plastic if every bijective nonexpansive self-map is an isometry. We prove that the hyperspace of nonempty compact subsets of every connected, locally finite, regu…
C*-convexity and C*-Polyhedron
Clayton Suguio Hida
A polyhedron in a Banach space is a family of points such that for every , there is a closed convex set such that and $\mathcal{X}\s…
Uncountable almost irredundant sets in nonseparable C*-algebras
Clayton Suguio Hida
In this article, we consider the notion of almost irredundant sets: A subset of a C*-algebra is called almost irredundant if and only if for every $a\in…
Large irredundant sets in operator algebras
Clayton Suguio Hida, Piotr Koszmider
A subset of a C*-algebra is called irredundant if no belongs to the C*-subalgebra of generated by $\mathcal X\setminus \{A\…
Two Cardinal Inequalities about Bidiscrete Systems
Clayton Suguio Hida
We consider the cardinal invariant defined by M. Džamonja and I. Juhász concerning bidiscrete systems. Using the relation between bidiscrete systems and irredundance for a com…
