Fixed point results for asymptotically HÃ¶lder nonexpansive type mappings

Cleon S. Barroso, Carlos SÃ©rgio R. da Silva

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

Einstein Warped Products with Einstein Base and Fiber

MÃ¡rcio Lemes de Sousa, TibÃ©rio Bittencourt de Oliveira Martins, Carlos Rodrigues da Silva

We study Einstein riemannian manifolds endowed with a warped product structure. We focus on the case in which both the base and the fiber are Einstein manifolds and establish neces…

On $L$ - $I ¨ $ -nonexpansive maps

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

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