Abstract : Stolz theorem states that for a n-dimensional simple connected spin manifold
where n  5, it admits a positive scalar curvature if and only if the α-invariant is zero. Weiping Zhang gave an equation to compute the α-invariant of spin complex hypersurfaces. In this talk, I use these tools to construct a family of submanifolds of generalised Bott towers which admit positive scalar curvatures.
