考虑二阶Hamilton系统:(HS)q.+ V′(q)= 0其中q=(q1,...,qN)∈ RN(N <$3)且V:RN\{e}→ R(e∈ RN)是具有奇异性的势,即,| V(q)|当q→ e时,在适当的假设下证明了(HS)的同宿轨道的存在性。我们的主要假设是Gordon [8]的强力条件和V的全局最大值的唯一性。
We consider the second order Hamiltonian system:(HS) q..+ V′(q)= 0 where q=(q 1,…, q N)∈ R N (N≧ 3) and V: R N\{e}→ R (e∈ R N) is a potential with a singularity, ie.,| V (q)|→∞ as q→ e. We prove the existence of a homoclinic orbit of (HS) under suitable assumptions. Our main assumptions are the strong force condition of Gordon [8] and the uniqueness of a global maximum of V.
