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

第11届威廉·罗文汉密尔顿几何和拓扑研讨会是一个为期五天的，三个和四个流形之间的相互作用指导研讨会，将在爱尔兰都柏林的汉密尔顿数学研究所（HMI）举行，2015年8月25日至29日。研讨会将包括为期两天的研究生和初级研究人员的迷你课程，然后是为期三天的系列讲座。William Rowan汉密尔顿几何和拓扑研讨会的目标是研究当前几何和拓扑研究中的常见主题和技术，并支持对这些领域感兴趣的初级研究人员。 本次研讨会将汇集三维和四维空间领域的领先研究人员与研究生和初级研究人员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融合将导致新的合作项目，并扩大参与者的研究视野今年的研讨会的目的是探讨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是由马丁·沙勒曼（圣巴巴拉）和大卫·盖伊（格鲁吉亚）提供的经典三维和四维流形理论的桥梁。今年研讨会的主要议题包括最近的工作有关的Schoenflies猜想，四维光滑庞加莱猜想，和“三等分”的4-流形。 研讨会网站将位于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.
