Kirchhoff paradigm over curved manifolds
WebAn odd dimensional positively curved manifold is known to be orientable (Synge), and its fundamental group is finite by the classical theorem of Bonnet and Myers. The … Web6 mei 2024 · We use an index-theoretic technique of Hitchin to show that the space of complete Riemannian metrics of nonnegative sectional curvature on certain open spin manifolds has nontrivial homotopy groups in infinitely many degrees. A new ingredient of independent interest is homotopy density of the subspace of metrics with cylindrical ends.
