Comparative Performance Evaluation of an Accuracy-Enhancing Lyapunov Solver
Information, 2019 Lyapunov equations are key mathematical objects in systems theory, analysis and design of control systems, and in many applications, including balanced realization algorithms, procedures for reduced order models, Newton methods for algebraic Riccati ...

High-Order Schemes for Nonlinear Fractional Differential Equations
Fractal and Fractional, 2022 We propose high-order schemes for nonlinear fractional initial value problems. We split the fractional integral into a history term and a local term. We take advantage of the sum of exponentials (SOE) scheme in order to approximate the history term.

Application of dm methods for problems with partial differential equations
Mathematical Modelling and Analysis, 2002 Two variants of applications of the Degenerate Matrix Method for solving problems with PDB are considered. Solutions of the simple testing problem and of one more complicated nonlinear problem with PDB of the fifth order are presented as examples.

Investigation of Egyptian Banks’ Competition through a Riesz–Caputo Fractional Model
Fractal and Fractional, 2023 In this paper, a four-dimensional competition model, driven by the Riesz–Caputo operator, is established. Then, the presented model’s uniqueness, existence, and stability are discussed.

A quantitative probabilistic investigation into the accumulation of rounding errors in numerical ODE solution. [PDF]
, 2009 We examine numerical rounding errors of some deterministic solvers for systems of ordinary differential equations (ODEs) from a probabilistic viewpoint. We show that the accumulation of rounding errors results in a solution which is inherently random and

Precalculated arrays-based algorithms for the calculation of the Riemann zeta-function
Vilnius University Open Series, 2022 In this paper, we continue the study of efficient algorithms for the computation of the Riemann zeta function on the complex plane. We introduce two precalculated arrays-based modifications of MB-method.
