泛Whitham族下的无穷维Frobenius流形

Infinite-dimensional Frobenius Manifolds Underlying the Universal Whitham Hierarchy

Shilin Ma, Chao-Zhong Wu, Dafeng Zuo

摘要:

在具有无穷远极点和可动极点的亚纯函数对空间上构造了一类无穷维Frobenius流形。这样的弗罗贝纽斯流形被证明是普遍的Whitham层次,这是一个扩展的dispersionless Kadomtsev-Petviashvili层次的基础。

英文摘要:

We construct a class of infinite-dimensional Frobenius manifolds on the spaces of pairs of meromorphic functions with a pole at infinity and a movable pole. Such Frobenius manifolds are shown to be underlying the universal Whitham hierarchy, which is an extension of the dispersionless Kadomtsev-Petviashvili hierarchy.
