$\TT^2$-cobordism of Quasitoric 4-Manifolds

arXiv:1009.0342 · doi:10.2140/agt.2012.12.2003

Abstract

We show the $\TT^2$-cobordism group of the category of 4-dimensional quasitoric manifolds is generated by the $\TT^2$-cobordism classes of $\CP^2$. We construct nice oriented $\TT^2$ manifolds with boundary where the boundary is the Hirzebruch surfaces. The main tool is the theory of quasitoric manifolds.
