Krylov subspace approximation for quadratic-bilinear differential system

International Journal of Systems Science, 2018
AbstractMany nonlinear systems with nonlinearities of the form 1/(k+x), ex, xα, ln(x) can be converted into quadratic-bilinear differential algebraic equations (QBDAEs) by introducing new variables and operating some algebra computations. Previous researches claim that the first two generalised transfer functions are enough to capture the dynamical ...

On Linear-Quadratic Differential Games for Fractional-Order Systems

Doklady Mathematics, 2023
Summary: We consider a finite-horizon two-person zero-sum differential game in which the system dynamics is described by a linear differential equation with a Caputo fractional derivative and the goals of control of the players are, respectively, to minimize and maximize a quadratic terminal-integral cost function.

Survey of results on quadratic differential systems

2021
Quadratic differential systems occur often in many areas of applied mathematics, in population dynamics [145], nonlinear mechanics [236, 237, 69], chemistry, electrical circuits, neural networks, laser physics, hydrodynamics [347, 328, 183, 191], astrophysics [80] and others [280, 154, 102].

Two Dimensional Homogeneous Quadratic Differential Systems

SIAM Review, 1978
The two-dimensional quadratic differential system (QDS) \[ \begin{gathered} \dot x = a_1 x^2 + b_1 xy + c_1 y^2 , \hfill \\ \dot y = a_2 x^2 + b_2 xy + c_2 y^2 \hfill \\ \end{gathered} \] where $( \cdot ) = {d} / {dt}$ and the coefficients are real constants is considered.

Bifurcation Analysis in Planar Quadratic Differential Systems with Boundary

International Journal of Bifurcation and Chaos, 2020
Given a planar quadratic differential system delimited by a straight line, we are interested in studying the bifurcation phenomena that can arise when the position on the boundary of two tangency points are considered as parameters of bifurcation. First, under generic conditions, we find a two-parametric family of quadratic differential systems with ...
