In the setting of hyperbolic spaces, we show that convergence Browder-type sequences and Halpern iterations respectively entail their viscosity version with a Rakotch map. We also hybrid Krasnoselskii-Mann iteration follows from Browder type sequence. Our results follow proof-theoretic techniques (proof mining). From an analysis theorems due to T. Suzuki, extract transformation rates for origin...

We construct a locally finite graph and a bounded geometry metric space which do not admit a quasi-isometric embedding into any uniformly convex Banach space. Connections with the geometry of c0 and superreflexivity are discussed. The question of coarse embeddability into uniformly convex Banach spaces became interesting after the recent work of G. Kasparov and G. Yu, who showed the coarse Novi...
