Abstract: In the first part, we will discuss a new proof of the existence of an open book decomposition for a closed non-orientable 3–manifold. This open book decomposition is analogous to a planar open book decomposition for a closed orientable 3–manifold. More precisely, we give an open book decomposition of a given closed non-orientable 3–manifold with the pages punctured Möbius bands and the monodromy product of Dehn twists. In the second part, we will discuss open book embeddings of closed non-orientable 3-manifolds into 5-manifolds. This is a joint work with Suhas Pandit and A Selvakumar. |
