Eclectic problems in topology, geometry and dynamics. This project aims to resolve a number of problems across several broad areas of pure mathematics. The problems all have a geometric or topological flavour, and some deal with dynamics in the qualitative sense. The problems share two common themes: they have group theoretic aspects and homological aspects. Specifically, the problems lie in the following areas:\r\n1. finite dimensional Lie algebras and their cohomology,\r\n2. low dimensional combinatorial geometry: graph drawings on surfaces,\r\n3. topological dynamics of group actions,\r\n4. differentiable group actions and foliation theory.\r\nThe most significant aims are to resolve two well known conjectures: Halperin's toral rank conjecture and Conway's thrackle conjecture.\r\n

拓扑，几何和动态方面的折衷问题。该项目旨在解决纯数学几个广泛领域的许多问题。这些问题都具有几何或拓扑味，有些问题从定性意义上讲。这些问题具有两个共同的主题：它们具有群体理论方面和同源方面。具体而言，问题在于以下领域：\ r \ n1。有限维谎言代数及其共同体，\ r \ n2。低维组合几何：表面上的图形图，\ r \ n3。小组动作的拓扑动态，\ r \ n4。可区分的群体行动和叶面理论。\ r \ n最重要的目的是解决两个众所周知的猜想：Halperin的Toral Rank猜想和Conway的Thrackle猜想。\ r \ n
