Hi,
Is there any criteria, except for the existence of a flat connection, for a foliated bundle E to be a suspension ( a foliated flat bundle)? For example, the Kronecker foliation on the torus is a suspension mathbbRtimesmathbbZmathbbS1 , i.e. its of the form MtimesGammaF, where Gamma acts freely and transitively on the manifold M and there is a free action rho:GammarightarrowDiff(F).
Note: The Kronecker foliation is induced by the vector field , afracpartialpartialx+bfracpartialpartialy on mathbbR2 with a,b constants.
The action of mathbbZ on mathbbRtimesmathbbS1 is given by:
(r,expiz).m=(r+m,exp(iz+malpha)) for some alphainmathbbR.
Thanks
