在本文中,我们给出了闭 3 流形 Lusternik-Schnirelmann 范畴的新简化计算。我们还描述了3-流形何时具有检测元件,并证明3-流形满足Ganea猜想的等式。
In this paper, we give a new simplied calculation of the Lusternik- Schnirelmann category of closed 3-manifolds. We also describe when 3-manifolds have detecting elements and prove that 3-manifolds satisfy the equality of the Ganea conjecture.
