有一个独特的真正的紧密接触3球

There is a unique real tight contact 3-ball

Ferit Ozturk, Nermin Salepci

摘要:

通过实紧切触结构证明了凸边界的3-球上存在唯一的实紧接触结构。我们还给出实紧立体环面的一个部分分类,其实结构是沿经度方向的对映映射和沿经度方向的恒等式。在证明中,我们使用了实切触流形上的切触邻域定理和不变凸曲面理论。

英文摘要:

We prove that there is a unique real tight contact structure on the 3-ball with convex boundary up to isotopy through real tight contact structures. We also give a partial classification of the real tight solid tori with the real structure being antipodal map along longitudinal and the identity along meridional direction. For the proofs, we use the real versions of contact neighborhood theorems and the invariant convex surface theory in real contact manifolds.
