Lyapunov Coefficients for Degenerate Hopf Bifurcations
Jorge Sotomayor, Luis Fernando Mello, Denis de Carvalho Braga
In this paper are studied the codimensions one, two, three and four Hopf bifurcations and the pertinent Lyapunov stability coefficients. Algebraic expressions obtained with compute…
Hopf Bifurcation in a Model for Biological Control
Jorge Sotomayor, Luis Fernando Mello, Danilo Braun Santos +1
In this paper we study the Lyapunov stability and Hopf bifurcation in a biological system which models the biological control of parasites of orange plantations.
Stability and Hopf Bifurcation in an Hexagonal Governor System With a Spring
Jorge Sotomayor, Luis Fernando Mello, Denis de Carvalho Braga
In this paper we study the Lyapunov stability and the Hopf bifurcation in a system coupling an hexagonal centrifugal governor with a steam engine. Here are given sufficient conditi…
Bifurcation Analysis of the Watt Governor System
Jorge Sotomayor, Luis Fernando Mello, Denis de Carvalho Braga
This paper pursues the study carried out by the authors in {\it Stability and Hopf bifurcation in the Watt governor system} \cite{smb}, focusing on the codimension one Hopf bifurca…
Stability and Hopf Bifurcation in the Watt Governor System
Jorge Sotomayor, Luis Fernando Mello, Denis de Carvalho Braga
In this paper we study the Lyapunov stability and Hopf bifurcation in a system coupling a Watt-centrifugal-governor with a steam-engine. Sufficient conditions for the stability of…
