Iterating Fixed Point via Generalized Mann’s Iteration in Convex b-Metric Spaces with Application

Complexity, 2021
This manuscript investigates fixed point of single-valued Hardy-Roger’s type F-contraction globally as well as locally in a convex b-metric space. The paper, using generalized Mann’s iteration, iterates fixed point of the abovementioned contraction ...

Phase portraits on the unit sphere of the stretch-twist-fold flow

Nonlinear Analysis, 2023
The so-called stretch-twist-fold flow consists in a Stokes flow depending on two parameters defined in a unit closed ball B that is associated with the motion of a fluid particle coming from the dynamo theory, and it models a mechanism for studying the ...

Closed balls for interpolating quasi-polynomials [PDF]

Computational & Applied Mathematics, 2011
This interesting paper studies interpolation in spatial points using so called `quasi-polynomials' of the form \[ {\mathbf f}(u)={\mathbf b}_1u^{\alpha_1}+{\mathbf b}_2u^{\alpha_2}+\cdots+{\mathbf b}_nu^{\alpha_n},\;u\in [0,\infty), \eqno{(\ast)} \] where \({\mathbf b}_1,{\mathbf b}_2,\dots{\mathbf b}_n\in{\mathbb C},\alpha_1,\alpha_2,\dots,\alpha_n\in{
