Degenerated Hopf bifurcation in a mathematical model of economical dynamics

Domenii publicaţii > Matematica + Tipuri publicaţii > Articol în revistã ştiinţificã

Autori: Laura Ungureanu

Editorial: Mathematics and Its Application/ Annals of the Academy of Romanian Scientists , 3, p.235-248, 2011.

Rezumat:

It is assumed that the dynamics of the capital of a firm is governed
by a Cauchy problem for a system of two nonlinear ordinary differential
equations containing three real parameters. In this paper we determine
a k > 3 order degenerated Hopf bifurcation point for this economical
model. To this aim the normal form technique is used.
