Logical Metatheorems for Abstract Spaces axiomatized in Positive Bounded Logic II: Metric spaces and the model-theoretic uniformity principle

Ulrich Kohlenbach, Morenikeji Neri, Jin Wei

We extend the proof-theoretic treatment of uniform bound extraction from normed structures axiomatized in positive bounded logic [Advances in Mathematics, 290:503-551, 2016] (as de…

On the Computational Content of Moduli of Regularity and their Logical Strength

Ulrich Kohlenbach

We continue the investigation into the computational status of the existence of moduli of regularity (and their use for rates of convergence) in the sense of Kohlenbach, Lopez and…

Fejér monotone sequences revisited

Ulrich Kohlenbach, Pedro Pinto

In this paper we introduce a localized and relativized generalization of the usual concept of Fejér monotonicity together with uniform and quantitative versions thereof and show th…

R.E. Bruck, proof mining and a rate of asymptotic regularity for ergodic averages in Banach spaces

Anton Freund, Ulrich Kohlenbach

We analyze a proof of Bruck to obtain an explicit rate of asymptotic regularity for Cesàro means in uniformly convex Banach spaces. Our rate will only depend on a norm bound and a…

On modified Halpern and Tikhonov-Mann iterations

Horatiu Cheval, Ulrich Kohlenbach, Laurentiu Leustean

We show that the asymptotic regularity and the strong convergence of the modified Halpern iteration due to T.-H. Kim and H.-K. Xu and studied further by A. Cuntavenapit and B. Pany…

Bounds for a nonlinear ergodic theorem for Banach spaces

Anton Freund, Ulrich Kohlenbach

We extract quantitative information (specifically, a rate of metastability in the sense of Terence Tao) from a proof due to Kazuo Kobayasi and Isao Miyadera, which shows strong con…
