A Modified Conjugate Descent Projection Method for Monotone Nonlinear Equations and Image Restoration

open access: yesIEEE Access, 2020
In this article, we propose a modified conjugate descent (CD) projection algorithm for solving system of nonlinear monotone equations with convex constraints.

An inertially constructed forward–backward splitting algorithm in Hilbert spaces

open access: yesAdvances in Difference Equations, 2021
In this paper, we develop an iterative algorithm whose architecture comprises a modified version of the forward–backward splitting algorithm and the hybrid shrinking projection algorithm.

A New Generalized Quasi-Newton Algorithm Based on Structured Diagonal Hessian Approximation for Solving Nonlinear Least-Squares Problems With Application to 3DOF Planar Robot Arm Manipulator

open access: yesIEEE Access, 2022
Many problems in science and engineering can be formulated as nonlinear least-squares (NLS) problems. Thus, the need for efficient algorithms to solve these problems can not be overemphasized.

Fractional order mathematical modeling of typhoid fever disease

open access: yesResults in Physics, 2022
This manuscript is devoted to focusing on the modeling and numerical solution of the dynamical model of Typhoid Fever. We use the Atangana–Baleanu operator with the Mittag–Leffler function in Caputo sense to study the behavior of the model.

Are corresponding points fixed? [PDF]

open access: yesVision Research, 2001
Several investigators have claimed that the retinal coordinates of corresponding points shift with vergence eye movements. Two kinds of shifts have been reported. First, global shifts that increase with retinal eccentricity; such shifts would cause a flattening of the horopter at all viewing distances and would facilitate fusion of flat surfaces ...

Convergence theorems for monotone vector field inclusions and minimization problems in Hadamard spaces

open access: yesAnalysis and Geometry in Metric Spaces, 2023
This article analyses two schemes: Mann-type and viscosity-type proximal point algorithms. Using these schemes, we establish Δ-convergence and strong convergence theorems for finding a common solution of monotone vector field inclusion problems, a ...

Fixed Point Logics

open access: yesThe Bulletin of Symbolic Logic, 2002
AbstractWe consider fixed point logics, i.e., extensions of first order predicate logic with operators defining fixed points. A number of such operators, generalizing inductive definitions, have been studied in the context of finite model theory, including nondeterministic and alternating operators. We review results established in finite model theory,

Layered Fixed Point Logic

open access: yes, 2012
We present a logic for the specification of static analysis problems that goes beyond the logics traditionally used. Its most prominent feature is the direct support for both inductive computations of behaviors as well as co-inductive specifications of ...

Fixed points of automorphisms [PDF]

open access: yesProceedings of the American Mathematical Society, 1976
We prove that the fixed point set of a compact Lie group of automorphisms of a Lie group has finitely many components if the Lie group does.
