A Numerical Method for a System of Fractional Differential-Algebraic Equations Based on Sliding Mode Control [PDF]

open access: goldMathematics, 2020
Fractional calculus is widely used in engineering fields. In complex mechanical systems, multi-body dynamics can be modelled by fractional differential-algebraic equations when considering the fractional constitutive relations of some materials.

Numerical differential continuation approach for systems of nonlinear equations with singular Jacobian [PDF]

open access: yesAUT Journal of Mathematics and Computing, 2022
It is well known that, one of the useful and rapid methods for a nonlinear system of algebraic equations is Newton’s method. Newton’s method has at least quadratic convergence when the Jacobian is a nonsingular matrix in a neighborhood of the solution ...

Linearisation of a second-order nonlinear ordinary differential equation

open access: yesActa Polytechnica, 2023
We analyse nonlinear second-order differential equations in terms of algebraic properties by reducing a nonlinear partial differential equation to a nonlinear second-order ordinary differential equation via the point symmetry f(v)∂v.
