复曲面拓扑中的高阶Whitehead积

Higher Whitehead products in toric topology

Jelena Grbic, Stephen Theriault

摘要:

本文研究了缺面复形K的矩角复形Z_k与Davis-Januskiewicz空间DJ(K)之间的关系。若K有n个顶点,则考虑同伦纤维化序列Z_k --> DJ(K)--> M,其中M是无限复射影空间的n个拷贝的乘积。我们观察到对这样的K,Z_k同伦等价于球面的楔形,并证明在这个等价下,映射Z_k -> DJ(K)同伦于高阶Whitehead积与迭代Whitehead积的楔形和.

英文摘要:

In this paper we study the relationship between the moment-angle complex Z_k and the Davis-Januskiewicz space DJ(K) for a class of complexes K named missing-face complexes. If K has n vertices we consider the homotopy fibration sequence Z_k --> DJ(K) --> M where M is a product of n copies of infinite complex projective space. We observe that for such K, Z_k is homotopy equivalent to a wedge of spheres, and then show that under this equivalence the map Z_k --> DJ(K) is homotopic to a wedge sum of higher Whitehead products and iterated Whitehead products.
