The article "Scalar Curvature Rigidity of Warped Product Metrics" was published on April 18, 2024: SIGMA 20 (2024), 035
The paper deals with rigidity of compact manifolds under assumptions on the scalar curvature and the mean curvature of the boundary. In particular, we solve a problem from Gromov's "Four Lectures on Scalar Curvature".
On the youtube channel Geometry Potsdam we have released a new math video on the winding number of closed plane curves. See here.
