Compact cosymplectic manifolds of positive constant phi-sectional curvature.
Locally conformal cosymplectic manifolds and time-dependent Hamiltonian systems
We show that locally conformal cosymplectic manifolds may be seen as generalized phase spaces of time-dependent Hamiltonian systems. Thus we extend the results of I. Vaisman for the time-dependent case.
Symplectic and cosymplectic foliations on cosymplectic manifolds.
