摘要: Allen-Cahn equation is a classical model arising from phase transition and closely related to the minimal surface theory. In dimension two, an important class of solutions to this equation is the so called multiple-end solutions. They have finite Morse index. While there already exist some results on the construction of these solutions near the boundary of the whole moduli space of multiple-end solutions, a general variational construction is still missing. In this talk we prove that there exists a family of 6-end solutions with prescribed slopes using minimax arguments. This is joint work with Jun Wang and Wen Yang.
