The William Rowan Hamilton Geometry and Topology Workshop; Dublin, Ireland, August 25 - 29, 2015

第11届William Rowan哈密尔顿几何和拓扑研讨会是一个为期五天的关于三到四个流形之间相互作用的指导研讨会，将于2015年8月25日至29日在爱尔兰都柏林的汉密尔顿数学研究所(HMI)举行。研讨会将包括为研究生和初级研究人员开设的为期两天的迷你课程，然后是为期三天的系列讲座。威廉·罗文·哈密尔顿几何和拓扑学研讨会的目标是调查当前几何和拓扑学研究中的共同主题和技术，并支持对这些领域感兴趣的初级研究人员。这次研讨会将把三维和四维空间领域的领先研究人员与研究生、学生和初级研究人员聚集在一起，调查这些领域研究的前沿问题。来自不同领域的专业知识的汇聚将导致新的合作项目，并拓宽参与者的研究视野。今年研讨会的目的是调查三维和四维空间研究中的共同主题和技术。为期两天的迷你课程将介绍马丁·沙尔曼(圣巴巴拉)和大卫·盖伊(佐治亚州)教授的经典三四流形理论。今年研讨会的主要议题包括最近与勋飞猜想有关的工作，4维光滑庞加莱猜想，以及4维流形的“三分割法”。研讨会的网站将位于http://www.hamilton.tcd.ie/events/gt/gt2015.htm

The 11th William Rowan Hamilton Geometry and Topology Workshop is a five-day, directed workshop on Interactions between three and four manifolds, to be held at the Hamilton Mathematical Institute (HMI) in Dublin, Ireland, August 25-29, 2015. The workshop will consist of a two-day mini-course for graduate students and junior researchers, followed by a three day lecture series. The goal of the William Rowan Hamilton Geometry and Topology Workshop is to investigate common themes and techniques in current research in geometry and topology and to support junior researchers interested in these areas. This workshop will bring together leading researchers in the fields of three and four dimensional spaces with graduates students and junior researchers to investigate questions at the forefront of research in these areas. The confluence of expertise from different areas will result in new collaborative projects, and in broadening the research horizons of the participantsThe purpose of this year's workshop is to investigate common themes and techniques in the research of three and four-dimensional spaces. The two-day mini course will be on bridging classical three- and four-manifold theory given by Martin Scharlemann (Santa Barbara) and David Gay (Georgia). Major topics of this year's workshop include recent work related to the Schoenflies conjecture, the 4-dimensional smooth Poincare conjecture, and "trisections" of 4-manifolds.
