𝕋<sup>2</sup>–cobordism of quasitoric 4–manifolds

Name: Work Video:
Duration: 3 min 30 s
Description: We show the T 2 -cobordism group of the category of 4-dimensional quasitoric manifolds is generated by the T 2 -cobordism classes of CP 2 .We construct nice oriented T 2 manifolds with boundary whose boundaries are the Hirzebruch surfaces.The main tool is the theory of quasitoric manifolds.
