Computing renormalized curvature integrals on Poincaré-Einstein manifolds

Jeffrey S. Case, Ayush Khaitan, Yueh-Ju Lin +2

We describe a general procedure for computing renormalized curvature integrals on Poincaré-Einstein manifolds. In particular, we explain the connection between the Gauss-Bonnet-ty…

Local and global conformal invariants of submanifolds

Jeffrey S. Case, Ayush Khaitan, Yueh-Ju Lin +2

We develop methods for constructing and computing conformal invariants of submanifolds, with a particular emphasis on conformal submanifold scalars and conformally invariant integr…

Non-homothetic complete periodic contact forms with constant Tanaka--Webster scalar curvature

Jeffrey S. Case, Yuya Takeuchi

We study the existence problem for complete contact forms with constant Tanaka--Webster scalar curvature on non-compact strictly pseudoconvex CR manifolds. We prove that, under mil…

A general nonuniqueness result for Yamabe-type problems for conformally variational Riemannian invariants

João Henrique Andrade, Jeffrey S. Case, Paolo Piccione +1

Given a conformally variational scalar Riemannian invariant , we identify a sufficient condition for a compact Riemannian manifold to admit finite regular coverings with many no…

Nonhomothetic complete periodic metrics with constant scalar curvature

João H. Andrade, Jeffrey S. Case, Paolo Piccione +1

We show that there are infinitely many pairwise nonhomothetic, complete, periodic metrics with constant scalar curvature that are conformal to the round metric on $S^n\setminus S^k…

A Gauss-Bonnet formula for the renormalized area of minimal submanifolds of Poincaré-Einstein manifolds

Jeffrey S. Case, C Robin Graham, Tzu-Mo Kuo +2

Assuming the extrinsic -curvature admits a decomposition into the Pfaffian, a scalar conformal submanifold invariant, and a tangential divergence, we prove that the renormalized…
