Frobenius子流形

Frobenius submanifolds

I. A. B. Strachan

摘要:

Frobenius子流形的概念-一个Frobenius流形的一个子流形,它本身是一个Frobenius流形相对于从原始流形诱导的结构-进行了研究。二维子流形特别简单。更一般地,给出了子流形是自然子流形的充分条件。这些思想可以通过由考克斯特群构造的弗罗贝纽斯流形以及控制CP ^2和CP ^1的量子上同调的弗罗贝纽斯流形\times CP ^1的例子来说明。

英文摘要:

The notion of a Frobenius submanifold - a submanifold of a Frobenius manifold which is itself a Frobenius manifold with respect to structures induced from the original manifold - is studied. Two dimensional submanifolds are particularly simple. More generally, sufficient conditions are given for a submanifold to be a so-called natural submanifold. These ideas are illustrated using examples of Frobenius manifolds constructed from Coxeter groups, and for the Frobenius manifolds governing the quantum cohomology of CP^2 and CP^1 \times CP^1.
