Abstract

Recently there are several works studying the finance model [Formula: see text] where [Formula: see text] and [Formula: see text] are positive parameters. The first objective of this paper is to show that this model exhibits one small-amplitude periodic solution emerging from a Hopf bifurcation at the equilibrium point [Formula: see text] and in the second one we show that this system does not have invariant algebraic surfaces for any value of the parameters.
