摘要
在本文中,我们确立了流形或更一般地,形式 Poincaré 对偶空间上的自由环路空间的常义同调和等变同调上的某些结构的存在性。这些结构,即环路积、环路括号和弦括号,由 Chas 和 Sullivan 在“弦拓扑”的总称下引入并研究。我们的方法基于 -代数的障碍理论和有理同伦论。所得的弦拓扑操作显然是同伦不变的。

Due to a strange glitch in the original submission a wrong TeX file was uploaded; this version hopefully corrects this error. This paper is a revision of the part of math.QA/0410621 which deals with string topology type operations and can be read independently. 9 pages
