曲面上正Dehn-扭曲的乘积

Products of Positive Dehn-twists on Surfaces

Feng Luo

摘要:

给定可定向闭曲面的3孔球面分解,证明了该曲面的每个保持定向的同胚与合成AB是同位素的,其中A是分解曲线上正Dehn扭曲的积,B是负Dehn扭曲的积。

英文摘要:

Given a 3-holed sphere decomposition of an orientable closed surface, it is shown that each orientation preserving homeomorphism of the surface is isotopic to a composition AB where A is a product of positive Dehn twists and B is a product of negative Dehn twists on the decomposition curves.
