Asymmetric heteroclinic double layers [PDF]

open access: yesESAIM: Control, Optimisation and Calculus of Variations, 2002
Summary: Let \(W\) be a non-negative function of class \(\hbox{C}^3\) from \(\mathbb{R}^2\) to \(\mathbb{R} \), which vanishes exactly at two points \({\mathbf a} \) and \({\mathbf b} \). Let \(S^1({\mathbf a} ,{\mathbf b} )\) be the set of functions of a real variable which tend to \({\mathbf a} \) at \(-\infty \) and to \({\mathbf b} \) at \(+\infty \
