We describe all F2Mm1,m2,n1,n2-natural affinors on the r-th order adapted frame bundle PrAY over (m1,m2, n1, n2)-dimensional fibered-fibered manifolds Y.

Contact topology and the structure of 5-manifolds with $π_{1} = ℤ_{2}$

Hansjörg Geiges, Charles B. Thomas (1998)

Annales de l'institut Fourier

Similarity:

We prove a structure theorem for closed, orientable 5-manifolds $M$ with fundamental group $π_{1} (M) = ℤ_{2}$ and second Stiefel-Whitney class equal to zero on $H_{2} (M)$ . This structure theorem is then used to construct contact structures on such manifolds by applying contact surgery to fake projective spaces and certain $ℤ_{2}$ -quotients of $S^{2} \times S^{3}$ .
