Isometric Splitting of Metrics Without Conjugate Points on
Stéphane Tchuiaga
We establish a global rigidity theorem for Riemannian metrics without conjugate points on three-manifolds of the form , where is a compact orientable surface o…
Metrizability and Dynamics of Weil Bundles
Stéphane Tchuiaga, Moussa Koivogui, Fidèle Balibuno
This paper bridges synthetic and classical differential geometry by investigating the metrizability and dynamics of Weil bundles. For a smooth, compact manifold \(M\) and a Weil al…
Geometric structures on Weil bundles: Canonical differential-geometric constructions
S. Tchuiaga, A. Ndiaye, C. Khoule +1
This paper investigates the transfer of classical geometric structures from a smooth manifold to its Weil bundle associated with a Weil algebra $\…
On the geometry of co-Hamiltonian diffeomorphisms
S. Tchuiaga, P. Bikorimana
This paper studies the geometry of the group of all co-Hamiltonian diffeomorphisms of a compact cosymplectic manifold . The fix-point theory for co-Hamiltonian diffeomor…
On cosymplectic dynamics
S. Tchuiaga, F. Houenou, P. Bikorimana
Cosymplectic geometry can be viewed as an odd dimensional counterpart of symplectic geometry. Likely in the symplectic case, a related property which is preservation of closed form…
