A polynomially accelerated fixed-point iteration for vector problems [PDF]

E-Journal of Analysis and Applied Mathematics
Fixed-point solvers are ubiquitous in nonlinear PDEs, yet their progress collapses whenever the Jacobian at the solution carries an eigenvalue arbitrarily close to one.

The Fixed Point Property of Strong Pseudocontraction Mapping

Journal of Harbin University of Science and Technology, 2020
In this paper, the iterative methods of fixed point of strong pseudocontraction mappings and accretive operators are studied in Banach spaces. A new threestep Ishikawa iteration is given.

A generalization of contraction principle

International Journal of Mathematics and Mathematical Sciences, 1981
In this paper, a generalized mean value contraction is introduced. This contraction is an extension of the contractions of earlier researchers and of the generalized mean value non-expansive mapping.

A fixed point theorem involving rational expressions without using Picard iteration

Topological Algebra and its Applications, 2021
In this paper, we consider a certain fixed point theorem that contains some rational expressions. The main aim of this paper is to prove a fixed point theorem without using the Picard iteration.

Four-Step Iteration Scheme to Approximate Fixed Point for Weak Contractions

Computers Materials & Continua, 2020
Fixed point theory is one of the most important subjects in the setting of metric spaces since fixed point theorems can be used to determine the existence and the uniqueness of solutions of such mathematical problems.

Fixed point iteration on pointsymmetric interference graphs [PDF]

, 1994
Interference graphs are used for performance analysis of multiprocessor interconnection networks. In order to model blocked transmissions, nodes can have three states: idle, active or blocked. The resulting steady state probability distribution has a non-

A Fixed Point Result with a Contractive Iterate at a Point [PDF]

Mathematics, 2019
In this manuscript, we define generalized Kincses-Totik type contractions within the context of metric space and consider the existence of a fixed point for such operators. Kincses-Totik type contractions extends the renowned Banach contraction mapping principle in different aspects.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
