Algebraic Topology: Old and New -- M.M. Postnikov Memorial Conference

这是一项为参加2007年6月18日至24日在波兰贝德勒沃的斯特凡·巴纳赫国际数学中心举行的代数拓扑学国际会议而提出的建议，以资助旅行(特别是年轻的美国人)和边际生存。这是一次有100多人参加的大型会议。将有十次全体演讲和三次平行会议，重点是(A)低维拓扑；(B)同伦理论-共形代数拓扑和椭圆上同调；以及(C)流形拓扑。会议的目的之一是促进这些领域之间的思想交流。这次会议的目的是将疏远的团体聚集在一起。在拓扑学的第一次大发展时期-上个世纪上半叶-拓扑学是一门统一的学科。大约在本世纪中叶，技术变得专业化，这门学科分成了低维、几何和代数三个分支。M·M·波斯尼科夫(1927-2004)是20世纪下半叶试图维护学科统一性的伟大人物之一。在这个新的世纪里，我们看到来自其他分支的技术的复兴。本次大会以这种重新趋同为主题。它还旨在将来自东欧和前苏联国家的拓扑学家以及来自美国和西欧的研究人员聚集在一起。有关这次会议的更多信息，请访问以下网页：http://at2007pm.org/

This is a proposal to fund travel (especially by young Americans) and marginal subsistence to attend an international conference on algebraic topology at the Stefan Banach International Mathematical Center in Bedlewo, Poland, June 18-24, 2007. This is planned as a substantial conference, with over 100 participants. There will be ten plenary talks and three parallel sessions focusing on (A) low dimensional topology; (B) homotopy theory---conformal algebraic topology and elliptic cohomology; and (C) manifold topology. One of the intents of the conference is to stimulate exchange of ideas between these areas. This conference aims at bringing together groups which have drifted apart. During its first great flowering---during the first half of the last century---topology was a unified subject. Around the middle of the century techniques became specialized and the subject broke up into low-dimensional, geometric, and algebraic branches. M. M.Postnikov (1927-2004) was one of the great figures from the second half of the 20th century trying to preserve the unity of the subject. In this new century we see a resurgence of use of techniques from other branches. This conference takes this re-convergence as its theme. It also aims to bring topologists from eastern European and former Soviet Union countries together with researchers from the United States and Western Europe.More information about the conference can be found on the web page:http://at2007pm.org/
