Non-negative scalar curvature on spin surgeries and Novikov conjecture
Jinmin Wang
Let be a closed aspherical manifold. Assume that the rational strong Novikov conjecture holds for . We show that on any spin surgery of along a region whose induced…

A scalar-mean curvature comparison theorem for manifolds with iterated conical singularities
Milan Jovanovic, Jinmin Wang
We use the Dirac operator method to prove a scalar-mean curvature comparison theorem for spin manifolds which carry iterated conical singularities. Our approach is to study the ind…
