The paper “Transversality of homoclinic orbits, the Maslov index, and the symplectic Evans function” co-authored by Frédéric Chardard (Université Jean Monnet) and Tom Bridges has been accepted for publication in Nonlinearity. Homoclinic orbits of Hamiltonian systems have two important geometric invariants: a Maslov index and a Lazutkin–Treschev invariant. A new relation between the two has […]
