An efficient variable stepsize rational method for stiff, singular and singularly perturbed problems

Alexandria Engineering Journal, 2022
In this article, a new iterative method of the rational type having fifth-order of accuracy is proposed to solve initial value problems. The method is self-starting, stable, consistent, and convergent, whereas local truncation error analysis has also ...

Approximation methods for hybrid diffusion systems with state-dependent switching processes : numerical algorithms and existence and uniqueness of solutions [PDF]

, 2010
By focusing on hybrid diffusions in which continuous dynamics and discrete events coexist, this work is concerned with approximation of solutions for hybrid stochastic differential equations with a state-dependent switching process.

A0-stability of variable stepsize BDF methods

Journal of Computational and Applied Mathematics, 1993
Die rückwärtigen Differentiationsformeln (BDF-Formeln) auf variablen Gittern werden in der Praxis in verschiedener Weise realisiert: als Formeln mit variablen Koeffizienten, als Formeln mit konstantem führenden Koeffizienten und als Formeln mit Interpolation beim Schrittweitenwechsel.

Attractors under discretizations with variable stepsize

Discrete & Continuous Dynamical Systems - A, 2005
The authors investigate the attractors and study the upper and lower semi-continuity results for generalized discretizations with variable step size. They also discuss the convergence to the exact attractor in the Hausdorff metric space and the connections to pullback attractors in cocycle dynamics.

A Parallel Best-Response Algorithm with Exact Line Search for Nonconvex Sparsity-Regularized Rank Minimization [PDF]

, 2017
In this paper, we propose a convergent parallel best-response algorithm with the exact line search for the nondifferentiable nonconvex sparsity-regularized rank minimization problem.

Subpixel Target Detection in Hyperspectral Imaging Using a Deep Neural Network With a Variable Stepsize Gradient Descent Method

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The main difficulty in using artificial neural networks, which are designed for classification, to detect a rare subpixel target in hyperspectral imaging is that there is typically only one actual target pixel available for training the neural networks ...

Almost Surely Asymptotic Stability of Exact and Numerical Solutions for Neutral Stochastic Pantograph Equations

Abstract and Applied Analysis, 2011
We study the almost surely asymptotic stability of exact solutions to neutral stochastic pantograph equations (NSPEs), and sufficient conditions are obtained.
