此計畫的主要目的是設法對觸拓樸給出幾何描述, 我們將對以下兩個主題有興趣: (1)從局部到全域:設法去瞭解我們將如何從局部性質過渡到全域性質. (2) 在觸拓樸下的幾何現象:去考察怎樣的幾何性質只發生在觸拓樸為tight 的背景空間. ;The main purpose of this project is trying to give geometrical descriptions for (contact) topology. We are interested in the following two subjects: (1) Local-to-global principle: To see how (or when) we can go from the local to the global. (2) Phenomena in tight contact structure: To investigate what scene can only play in tight contact structure.
