The Maslov Indices of Hamiltonian Periodic Orbits
maurice de Gosson, Serge de Gosson
We use the properties of the Leray index to give precise formulas in arbitrary dimensions for the Maslov index of the monodromy matrix arising in periodic Hamiltonian systems. We c…

Determinant of Laplacians on Heisenberg Manifolds
Kenro Furutani, Serge de Gosson
We give an integral representaion of the zeta-reguralized determinant of Laplacians on three dimensional Heisenberg manifolds, and study a behaivior of the values when we deform th…
