Operator means deformed by a fixed point method [PDF]
arXiv, 2017 By means of a fixed point method we discuss the deformation of two-variable and multivariate operator means of positive definite matrices/operators. It is shown that the deformation of any operator mean in the Kubo–Ando sense becomes again an operator ...

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.

A note on a fixed-point method for deconvolution [PDF]
Statistics, 2017 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 $\alpha \in [0, 1 2 [$.

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 ...

Hybrid Viscosity Iterative Method for Fixed Point, Variational Inequality and Equilibrium Problems [PDF]
Fixed Point Theory and Applications, 2010 We introduce an iterative scheme by the viscosity iterative method for finding a common element of the solution set of an equilibrium problem, the solution set of the variational inequality, and the fixed points set of infinitely many nonexpansive ...

A Fixed-Point of View on Gradient Methods for Big Data [PDF]
arXiv, 2017 Interpreting gradient methods as fixed-point iterations, we provide a detailed analysis of those methods for minimizing convex objective functions. Due to their conceptual and algorithmic simplicity, gradient methods are widely used in machine learning for massive data sets (big data).
