Abstract |
|
Thomas, using an obstruction theory approach, evaluated the index of a tangent 2-field on Mm,m ≡ 1(4) if M is a spin manifold. Atiyah using the Atiyah-Singer index theorem evaluated the index for all orientable manifolds. The purpose here is to give a proo f of Atiyah’s result in the spirit of Thomas’ work. |
