Abstract

Let D(t ₀ ,ε) be the splitting distance of the stable and unstable manifold of a time-periodic second order equation. We expand D(t ₀ ,ε) as a formal power series in ε as D(t ₀ ,ε)=E ₀ (t ₀ )+εE ₁ (t ₀ )+⋯+ε ⁿ E _n (t ₀ )+⋯. In this paper we derive an explicit integral formula for E ₁ (t ₀ ). We also evaluate E ₁ (t ₀ ) to prove the existence of homoclinic tangles for an equation to which the Poincaré/Melnikov method fails to apply.
