虚弦及其配边性

Virtual strings and their cobordisms

Vladimir Turaev

摘要:

虚弦是曲面上闭曲线的自相交的一种形式。我们研究了弦的代数不变式以及弦集合上的两个等价关系:同伦和配边。我们证明了弦的同伦不变量构成一个无穷维李群。我们还讨论了虚弦和虚结之间的联系。

英文摘要:

A virtual string is a scheme of self-intersections of a closed curve on a surface. We study algebraic invariants of strings as well as two equivalence relations on the set of strings: homotopy and cobordism. We show that the homotopy invariants of strings form an infinite dimensional Lie group. We also discuss connections between virtual strings and virtual knots.
