Hybrid Fixed-Point Fixed-Stress Splitting Method for Linear Poroelasticity [PDF]

Geosciences, 2019
Efficient and accurate poroelasticity models are critical in modeling geophysical problems such as oil exploration, gas-hydrate detection, and hydrogeology. We propose an efficient operator splitting method for Biot’s model of linear poroelasticity

General fixed-point method for solving the linear complementarity problem

AIMS Mathematics, 2021
In this paper, we consider numerical methods for the linear complementarity problem (LCP). By introducing a positive diagonal parameter matrix, the LCP is transformed into an equivalent fixed-point equation and the equivalence is proved.

Strong convergence of a self-adaptive inertial Tseng's extragradient method for pseudomonotone variational inequalities and fixed point problems [PDF]

Open Mathematics, 2022
In this paper, we study the problem of finding a common solution of the pseudomonotone variational inequality problem and fixed point problem for demicontractive mappings.

A note on a fixed-point method for deconvolution [PDF]

Statistics, 2016
In this paper we study a particular multidimensional deconvolution problem. The distribution of the noise is assumed to be of the form $G(dx) = (1 − \alpha)\delta(dx) + \alpha g(x)dx$, where $\delta$ is the Dirac mass at $0\in R^d$ , $g : R^d → [0, \infty)$ is a density and $\alpha \in [0, 1 2 [$.

Acceleration methods for fixed point iterations [PDF]

Acta Numerica
A pervasive approach in scientific computing is to express the solution to a given problem as the limit of a sequence of vectors or other mathematical objects. In many situations these sequences are generated by slowly converging iterative procedures, and this led practitioners to seek faster alternatives to reach the limit.

Revisiting Blasius Flow by Fixed Point Method [PDF]

Abstract and Applied Analysis, 2014
The well-known Blasius flow is governed by a third-order nonlinear ordinary differential equation with two-point boundary value. Specially, one of the boundary conditions is asymptotically assigned on the first derivative at infinity, which is the main ...

The Fixed Point Method for Fuzzy Approximation of a Functional Equation Associated with Inner Product Spaces [PDF]

, 2010
Th. M. Rassias (1984) proved that the norm defined over a real vector space 𝑋 is induced by an inner product if and only if for a fixed integer 𝑛≥2,∑𝑛𝑖=1‖𝑥𝑖∑−(1/𝑛)𝑛𝑗=1𝑥𝑗‖2=∑𝑛𝑖=1‖𝑥𝑖‖2∑−𝑛‖(1/𝑛)𝑛𝑖=1𝑥𝑖‖2 holds for all 𝑥1,…,𝑥𝑛∈𝑋.

An extrapolated fixed-point optimization method for strongly convex smooth optimizations

AIMS Mathematics
In this work, we focused on minimizing a strongly convex smooth function over the common fixed-point constraints. We proposed an extrapolated fixed-point optimization method, which is a modified version of the extrapolated sequential constraint method ...

Fixed Point Iteration Method

MANAS: Journal of Engineering, 2013
We discuss the problem of finding approximate solutions of the equation x)0 f()0 (1) In some cases it is possible to find the exact roots of the equation (1) for example when f(x) is a quadratic on cubic polynomial otherwise, in general, is interested

Ulam stability of functional equations in 2-Banach spaces via the fixed point method

Journal of Fixed Point Theory and Applications, 2021
Using the fixed point method, we prove the Ulam stability of two general functional equations in several variables in 2-Banach spaces. As corollaries from our main results, some outcomes on the stability of a few known equations being special cases of ...
