1 Introduction

A unitary struture ${{Authors|Taras Panov}} == Introduction == <wikitex>; A unitary struture $\bar \nu$ on a manifold $M$ is a choice of weak complex structure on the stable normal bundle of $M$. By the [[B-Bordism#Pontrjagin-Thom isomorphism|Pontrjagin-Thom isomorphism]] the bordism groups of closed unitary manifolds $(M, \bar \nu)$ are isomorphic to the homotopy groups of the Thom spectrum $MU$, $\Omega_*^{U} \cong \pi_n(MU)$.
