[Un contre-exemple à la décomposition lisse de Hodge pour des feuilletages généraux et à une classe de formules de trace dynamique]
Nous construisons un feuilletage à feuilles denses et de codimension deux sur la variété de Heisenberg tel que la décomposition de Hodge feuilletée ne soit pas vérifiée. Nous démontrons aussi qu'un certain type de formules de trace dynamique reliant les orbites périodiques aux traces sur la cohomologie feuilletée, ne sont pas vraies pour des flots arbitraires.
We construct a two dimensional foliation with dense leaves on the Heisenberg nilmanifold for which smooth leafwise Hodge decomposition does not hold. It is also shown that a certain type of dynamical trace formulas relating periodic orbits with traces on leafwise cohomologies does not hold for arbitrary flows.
Keywords: Hodge decomposition, foliation, dynamical trace formula, nilmanifold
