Applications of compact multipliers to algebrability of $(ℓ_{\infty} ∖ c_{0}) \cup {0}$ and $(B (ℓ_{2} (N)) ∖ K (ℓ_{2} (N)) \cup {0} .$

Willian Franca, Jorge J. Garcés

We introduce a generator-counting refinement of algebrability for abelian $C^{*}$ -algebras and related Banach algebras. Given an abelian $C^{*}$ -algebra $A$ , we define $(C^{*})$ -genalgeb…

Commuting maps on rank- $k$ matrices

Willian Versolati Franca

Let $n \geq 2$ be a natural number. Let $M_{n} (K)$ be the ring of all $n \times n$ matrices over a field $K$ . Fix natural number $k$ satisfying $1 < k \leq n$ . Under a m…
