Generalized homoclinic solutions for the Swift–Hohenberg equation

AbstractThis paper considers the Swift–Hohenberg equationu⁗+βu″+u3−u=0,β>0. Applying a perturbation method and adjusting some phase shift constants, we prove that it has a homoclinic solution connecting a periodic solution (called generalized homoclinic solution, thereafter) near the origin for each positive constant β, which is a new result
