Bundle functors on all foliated manifold morphisms have locally finite order J. Kurek, W. M. Mikulski (2008) Annales Polonici Mathematici We prove that any bundle functor F:ℱol → ℱℳ on the category ℱ olof all foliated manifolds without singularities and all leaf respecting maps is of locally finite order.
