圆上Torus丛上闭1-形式的接触变形

Contact deformations of closed 1-forms on Torus bundles over the circle

Hamidou Dathe, Philippe Rukimbira

摘要:

如果一个闭的3-流形M支持一个闭的、非奇异的、无理的1-形式,它线性变形为切触形式,那么M支持一个K-切触形式。在3-环面上,一个闭的非奇异1-形式线性变形为接触形式当且仅当它是纤维化1-形式。在圆上的任何其他2-torus丛上,每个闭合的非奇异1-形式线性变形为切触形式。

英文摘要:

If a closed 3-manifold M supports a closed, nonsingular, irrational 1-form which linearly deforms into contact forms, then M supports a K-contact form. On the 3-torus, a closed nonsingular 1-form deforms linearly into contact forms if and only if it is a fibration 1-form. on any other 2-torus bundle over the circle, every closed, nonsingular 1-form deforms linearly into contact forms.
