On $\alpha$-Firmly Nonexpansive Operators in $r$-Uniformly Convex Spaces

Arian Bërdëllima, Gabriele Steidl

We introduce the class of $\alpha$-firmly nonexpansive and quasi $\alpha$-firmly nonexpansive operators on $r$-uniformly convex Banach spaces. This extends the existing notion from Hilbert s…
