Objectives
Conformal geometry is the study of the set of angle-preserving (conformal) transformations on a space. While in two dimensions, this is precisely the geometry of Riemann surfaces, in dimensions three and above the answer opens up many new different subjects, leading to the very wide field that is conformal geometry.

The first question is to find conformal invariants, or more specifically, conformally covariant operators, that  is, operators which satisfy some invariant  property under conformal change of metrics on a manifold, and its associated curvature.  The model example is the Laplace-Beltrami operator, in relation to the Yamabe problem.  The Yamabe equation is a second order, semilinear PDE; we would like to understand higher order or fully non-linear generalizations, such as the Paneitz operators together with Q-curvature, or the \sigma_k equation. As a consequence, new interesting directions in PDEs have been opened up, where existence or regularity theory is not developed  as much.

Lately, there has been a lot of interest in the study of non-local, conformally covariant operators of fractional order constructed from Poincaré-Einstein metrics. While they are natural objects in other areas as probability, their geometrical meaning is not yet well understood. Particularly, the study of Poincaré-Einstein metrics has been and continues to be a rich source of activity relating conformal and Riemannian geometry. These are complete
Einstein metrics which are asymptotically hyperbolic at infinity. Their boundary at infinity invariantly inherits a conformal structure. The asymptotic behavior of the metric encodes a great deal of information about the conformal structure at infinity, and this has led to new constructions and progress in conformal geometry. On the other hand, there are many analytic problems concerning the existence, uniqueness and regularity of Poincaré-Einstein metrics with a given conformal infinity and many open problems. This topic is stimulated by its role in the AdS/CFT correspondence in Physics.

In CR geometry there are formal similarities with conformal geometry. For example, there are conformally covariant operators analogous to the conformal Laplacian and the Paneitz operators. While these operators also come with associated Q-curvature quantities, their geometric/analytic meaning is quite different from conformal geometry. The analysis of these operators is closely connected with the geometry of the pseudoconvex manifolds which they may bound, hence of interest in several complex variables.​
