本文研究了与过扭接触结构相容的三个流形上的开书。我们表明,存在一定的弧,称为清醒弧,是一个充分条件的开放的书被overtwisted,是必要的,以稳定的积极的霍普夫带。利用这些技巧,我们证明了一些作为辛构形边界的开书是过扭曲的,回答了Gay在(9)中提出的一个问题。AMS分类57 R17; 57 M99
We study open books on three manifolds which are compat- ible with an overtwisted contact structure. We show that the existence of certain arcs, called sobering arcs, is a sufficient condition for an open book to be overtwisted, and is necessary up to stabilization by positive Hopf-bands. Using these techniques we prove that some open books arising as the boundary of symplectic configurations are overtwisted, answering a question of Gay in (9). AMS Classification 57R17; 57M99
