2-torus Manifolds, Cobordism and Small Covers

چکیده
Abstract. Let Mn be the set of equivariant unoriented cobordism classes of all ndimensional 2-torus manifolds, where an n-dimensional 2-torus manifold M is a smooth closed manifold of dimension n with effective smooth action of a rank n 2-torus group (Z2) . Then Mn forms an abelian group with respect to disjoint union. This paper determines the group structure of Mn and shows that each class of Mn contains a small cover as its representative in the case n = 3.

Equivariant Classification of 2-torus Manifolds
In this paper, we consider the equivariant classification of locally standard 2-torus manifolds. A 2-torus manifold is a closed smooth manifold of dimension n with an effective action of a 2-torus group (Z2) n of rank n, and it is said to be locally standard if it is locally isomorphic to a faithful representation of (Z2) n on R. The orbit space Q of a locally standard 2-torus M by the action i...
متن کاملToric Topology and Complex Cobordism
We plan to discuss how the ideas and methodology of Toric Topology can be applied to one of the classical subjects of algebraic topology: finding nice representatives in complex cobordism classes. Toric and quasitoric manifolds are the key players in the emerging field of Toric Topology, and they constitute a sufficiently wide class of stably complex manifolds to additively generate the whole c...
متن کاملTopological Types of 3-dimensional Small Covers
In this paper we study the (equivariant) topological types of a class of 3dimensional closed manifolds (i.e., 3-dimensional small covers), each of which admits a (Z2) -action such that its orbit space is a simple convex 3-polytope. We introduce six equivariant operations on such 3-dimensional closed manifolds. These six operations are interesting because of their combinatorial natures. Then we ...
متن کاملThe Relation between Compact and Non-compact Equivariant Cobordisms
We show that the theory of stable complex G-cobordisms, for a torus G, is embedded into the theory of stable complex G-cobordisms of not necessarily compact manifolds equipped with proper abstract moment maps. Thus the introduction of such non-compact cobordisms in the stable complex G-cobordism theory does not lead to new relations. 1. Proper abstract moment maps. The main objective of this pa...

It is shown that a small cover (resp. real moment-angle manifold) over a simple polytope is an infra-solvmanifold if and only if it is diffeomorphic to a real Bott manifold (resp. flat torus). Moreover, we obtain several equivalent conditions for a small cover being homeomorphic to a real Bott manifold. In addition, we study Riemannian metrics on small covers and real momentangle manifolds with...
