標題: | Asymptotic spectral flow for Dirac operators of disjoint Dehn twists | 作者: | CHUNG-JUN TSAI | 關鍵字: | Dehn twist; Dirac spectral flow; Open book decomposition | 公開日期: | 2014 | 卷: | 18 | 期: | 4 | 起(迄)頁: | 633-686 | 來源出版物: | Asian Journal of Mathematics | 摘要: | Let Y be a compact, oriented 3-manifold with a contact form a. For any Dirac operator D, we study the asymptotic behavior of the spectral flow between D and D + cl(-ir/2 a) as r → ∞. If a is the Thurston-Winkelnkemper contact form whose monodromy is the product of Dehn twists along disjoint circles, we prove that the next order term of the spectral flow function is O(r). © 2014 International Press. |
