Abstract
We look for homoclinic solutions for a class of second order autonomou s Hamiltonian systems in R-2 with a potential V having a strict global maximum at the origin and a finite set S subset of R-2 of singulariti es, namely V(x) --> -infinity as dist(x,S) --> 0. We prove that if V s atisfies a suitable geometrical property then for any k epsilon N the system admits a homoclinic orbit turning k times around a singularity xi epsilon S. (C) Elsevier, Paris.
