Abstract

Assume that the linear part at a singular point p0of a C4differential system Y0in ℝ4has eigenvalues ±αi and ±βi such that β/α = 1/3. In the main result of the paper we exhibit a one-parameter family of systems Yεfor ε ∈ (-δ0, +δ0) where is shown that the original vector field around p0can bifurcate in 0, 1, 2, 3 or 4 one-parameter families of periodic orbits. The tool for proving such a result is the averaging theory for non-C1differentiable system. Moreover, assuming now that Yεis a one-parameter family of ℤ2-reversible polynomial vector fields of degree 5, we show that it can bifurcate in 0 or 2 one-parameter families of periodic orbits.
