Equivariant index theory and non-positively curved manifolds.
An elliptic differential operator D on a compact manifold M is a Fredholm operator. The only topological invariant for a Fredholm operator is the Fredholm index [Dou72], which is defined to be dim(kerD) − dim(cokerD). Fredholm index is a homotopy invariant. The Atiyah-Singer index theorem calculates...
