We present work in progress towards an intuitionistic version of Applicative Matching Logic. We introduce a semantics based on complete Heyting algebras, and propose a proof system which we prove to be sound relative to this semantics.

In this note we apply a lemma due to Sabach and Shtern to compute linear rates of asymptotic regularity for Halpern-type nonlinear iterations studied in optimization and nonlinear analysis.

In this paper we generalize the strongly convergent Krasnoselskii- Mann-type iteration for families of nonexpansive mappings defined recently by Boţ and Meier in Hilbert spaces to the abstract setting of W - hyperbolic spaces and we compute effective rates of asymptotic regularity for our generalization. This also generalizes recent results by Leuştean and the author on the Tikhonov-Mann iteration from single mappings to families of mappings.
