Fixed point results for asymptotically Hölder nonexpansive type mappings

Cleon S. Barroso, Carlos Sérgio R. da Silva

In this work, we extend Goebel-Kirk fixed point theorems to the setting of mappings of asymptotically Hölder-nonexpansive type. By providing several non-trivial examples, we show t…

On $L$ - $ω$ -nonexpansive maps

Cleon S. Barroso, Jeimer V. Bedoya, Carlos S. R. da Silva

We consider $L$ - $ω$ -nonexpansive maps $T : K \to K$ on a convex subset $K$ of a Banach space $X$ , i.e., maps in which $ω_{T} (δ) \leq L δ + ω (δ)$ with $L \in [0, 1]$ , $ω$ being a modulus…

High-Order regularity for fully nonlinear elliptic transmission problems under weak convexity assumption

G. C. Ricarte, C. S. Barroso, L. S. Tavares

This paper studies Schauder theory to transmission problems modelled by fully nonlinear uniformly elliptic equations of second order. We focus on operators F that fails to be conca…
