Riemannian foliation with exotic tori as leaves
We construct smooth fiber bundles such that the fibers are exotic tori and the total space has finite abelian fundamental group. This gives examples of a Riemannian foliation on a closed manifold
Equivariant de Rham cohomology: theory and applications
This is a survey on the equivariant cohomology of Lie group actions on manifolds, from the point of view of de Rham theory. Emphasis is put on the notion of equivariant formality, as well as on
The Flow of Gauge Transformations on Riemannian Surface with Boundary
We consider the gauge transformations of a metric G-bundle over a compact Riemannian surface with boundary. By employing the heat flow method, the local existence and the long time existence of
Optimal Symplectic Connections on Holomorphic Submersions
The main result of this paper gives a new construction of extremal Kähler metrics on the total space of certain holomorphic submersions, giving a vast generalisation and unification of results of
Hamiltonian structures for projectable dynamics on symplectic fiber bundles
The Hamiltonization problem for projectable vector fields on general symplectic fiber bundles is studied. Necessary and sufficient conditions for the existence of Hamiltonian structures in the class
Reductions of Dynamics on Second Iterated Bundles of Lie Groups
We consider trivializations of second iterated bundles of a Lie group that preserve lifted group structures. With such a trivialization, we elaborate Hamiltonian dynamics on cotangent, Lagrangian
Hörmander's condition for normal bundles on spaces of immersions
Several representations of geometric shapes involve quotients of mapping spaces. The projection onto the quotient space defines two sub-bundles of the tangent bundle, called the horizontal and
An 1-differentiable cohomology induced by a vector field
A new cohomology, induced by a vector field, is defined on pairs of differential forms (1– differentiable forms) in a manifold. It is proved a link with the classical de Rham cohomology and an
DIFFERENTIAL GEOMETRY OF
As the third of our series of papers on differential geometry of microlinear Frolicher spaces is this paper devoted to the Frolicher-Nijenhuis calculus of their named bracket. The main result is that
Variational calculus on Lie algebroids
It is shown that the Lagrange's equations for a Lagrangian system on a Lie algebroid are obtained as the equations for the critical points of the action functional defined on a Banach manifold of

Lie group valued moment maps
We develop a theory of "quasi"-Hamiltonian G-spaces for which the moment map takes values in the group G itself rather than in the dual of the Lie algebra. The theory includes counterparts of
