Local convergence for an eighth order method for solving equations and systems of equations

open access: yesNonlinear Engineering, 2019
The aim of this study is to extend the applicability of an eighth convergence order method from the k−dimensional Euclidean space to a Banach space setting.

Convergence criteria of Newton’s method on Lie groups

open access: yesFixed Point Theory and Applications, 2013
In the present paper, we study Newton’s method on Lie groups (independent of affine connections) for finding zeros of a mapping f from a Lie group to its Lie algebra.

GLOBAL CONVERGENCE OF THE TMR METHOD FOR UNCONSTRAINED OPTIMIZATION PROBLEMS

open access: yes, 2017
Conjugate gradient methods are probably the most famous iterative methods for solving large scale optimization problems in scientific and engineering computation, characterized by the simplicity of their iteration and their low memory requirements. It is

Multipoint secant and interpolation methods with nonmonotone line search for solving systems of nonlinear equations

open access: yes, 2017
Multipoint secant and interpolation methods are effective tools for solving systems of nonlinear equations. They use quasi-Newton updates for approximating the Jacobian matrix.

Computing Dynamic Output Feedback Laws

open access: yes, 2003
The pole placement problem asks to find laws to feed the output of a plant governed by a linear system of differential equations back to the input of the plant so that the resulting closed-loop system has a desired set of eigenvalues.

A Macaulay2 package for characteristic classes and the topological Euler characteristic of complex projective schemes [PDF]

open access: yes, 2013
The Macaulay2 package CharacteristicClasses provides commands for the computation of the topological Euler characteristic, the degrees of the Chern classes and the degrees of the Segre classes of a closed subscheme of complex projective space.

Exploring homotopy with hyperspherical tracking to find complex roots with application to electrical circuits

open access: yesOpen Mathematics
In the field of applied sciences, systems are frequently modeled using mathematical frameworks that include systems of nonlinear algebraic equations. Identifying their roots, whether real or complex, is of critical importance.

Blended General Linear Methods based on Boundary Value Methods in the GBDF family [PDF]

open access: yes, 2009
Among the methods for solving ODE-IVPs, the class of General Linear Methods (GLMs) is able to encompass most of them, ranging from Linear Multistep Formulae (LMF) to RK formulae.

On the Curvature of the Central Path of Linear Programming Theory

open access: yes, 2003
We prove a linear bound on the average total curvature of the central path of linear programming theory in terms on the number of independent variables of the primal problem, and independent on the number of constraints.Comment: 24 pages. This is a fully

Two-unitary complex Hadamard matrices of order 36

open access: yesSpecial Matrices
A family of two-unitary complex Hadamard matrices (CHMs) of size 36 stemming from a particular matrix is constructed. Every matrix in this orbit remains unitary after operations of partial transpose and reshuffling which makes it a distinguished subset ...
