On Some Relations between Accretive, Positive, and Pseudocontractive Operators and Passivity Results in Hilbert Spaces and Nonlinear Dynamic Systems [PDF]
, 2017 This paper investigates some parallel relations between the operators (I-G) and G in Hilbert spaces in such a way that the pseudocontractivity, asymptotic pseudocontractivity, and asymptotic pseudocontractivity in the intermediate sense of one of them ...

Almost Multi-Cubic Mappings and a Fixed Point Application [PDF]
Sahand Communications in Mathematical Analysis, 2020 The aim of this paper is to introduce $n$-variables mappings which are cubic in each variable and to apply a fixed point theorem for the Hyers-Ulam stability of such mapping in non-Archimedean normed spaces.

Angewandte Chemie, EarlyView.Hybrid physics and deep‐learning enabled design methods identified miniprotein binders to Flpp3 (Francisella‐like lipoprotein), a key virulence factor from Francisella tularensis. Multiple candidates with nanomolar to picomolar binding affinities were obtained using yeast surface display screening and further experimental optimization.

Stability of the Fréchet Equation in Quasi-Banach Spaces
Mathematics, 2020 We investigate the Hyers–Ulam stability of the well-known Fréchet functional equation that comes from a characterization of inner product spaces. We also show its hyperstability on a restricted domain. We work in the framework of quasi-Banach spaces.

Ulam type stability problems for alternative homomorphisms [PDF]
, 2014 We introduce an alternative homomorphism with respect to binary operations and investigate the Ulam type stability problem for such a mapping. The obtained results apply to Ulam type stability problems for several important functional equations ...
