Regularization and Minimization of Γ1-structures
- GAËL MEIGNIEZ
For Γ1-structures on 3-manifolds, we give a very simple proof of Thurston’s regularization theorem, first proved in , without using Mather’s homology equivalence. Moreover, in the co-orientable case, the resulting foliation can be chosen of a precise kind, namely an “open book foliation modified by suspension”. There is also a model in the non co-orientable case.
