Bordism and projective space bundles

Bordism and projective space bundles

We prove that total spaces of CP^2-bundles generate the oriented cobordism ring Omega*. Combined with the surgery lemma [8, 22], this yields a somewhat different proof of Gromov’s and Lawson’s theorem [8] that all simply connected non-spin manifolds of dimension at least 5 admit metrics of positive...
