Title: Nodal sets and negative eigenvalues in conformal geometry
Abstract: We discuss conformal invariants that arise from
eigenfunctions with eigenvalue 0 of the conformal Laplacian
(and other conformally covariant operators). We also discuss
some results about negative eigenvalues of the conformal Laplacian,
as well as some generalizations for manifolds with boundary
and discrete Laplacians (as time permits)
