A highly accurate numerical method for solving boundary value problem of generalized Bagley‐Torvik equation

Mathematical Methods in the Applied Sciences, EarlyView.
A highly accurate numerical method is given for the solution of boundary value problem of generalized Bagley‐Torvik (BgT) equation with Caputo derivative of order 0<β<2$$ 0<\beta <2 $$ by using the collocation‐shooting method (C‐SM). The collocation solution is constructed in the space Sm+1(1)$$ {S}_{m+1}^{(1)} $$ as piecewise polynomials of degree at ...

Poincaré Compactification for Non-polynomial Vector Fields [PDF]

Qualitative Theory of Dynamical Systems, 2020
In this work a theorical framework to apply the Poincaré compactification technique to locally Lipschitz continuous vector fields is developed. It is proved that these vectors fields are compactifiable in the n-dimensional sphere, though the compactified vector field can be identically null in the equator.

Complete polynomial vector fields on the complex plane

Topology, 2004
Let \(v=P(z,w)\partial/\partial z + Q(z,w)\partial/\partial w\) be a complete polynomial vector field on the complex plane \(\mathbb C^ 2\). The author proves that then \(v\) is, up to a polynomial change of coordinates, of one of the three types specified in the main theorem of his paper.
