Jeff ViaclovskyUniversity of WisconsinYamabe invariants and limits of self-dual hyperbolic monopole metricsConsider the self-dual conformal classes on n # CP^2 discovered by LeBrun. These depend upon a choice of n points in hyperbolic 3-space, called monopole points. I will discuss the limiting behavior of various constant scalar curvature metrics in these conformal classes as the points approach each other, or as the points tend to the boundary of hyperbolic space. There is a close connection to the orbifold Yamabe problem (which I will show is not always solvable, in contrast with the case for compact manifolds).

While it is topological in two dimensions and is essentially the Weyl action in four dimensions, in the higher dimensional cases its geometric meaning remains mysterious. Graham and Hirachi have shown that the first metric variation of the total Q-curvature coincides with the Fefferman-Graham obstruction tensor. In this talk, the second variational formula will be presented, and it will be made explicit especially for conformally Einstein manifolds. The positivity of the second variation will be discussed in connection with the smallest eigenvalue of the Lichnerowicz Laplacian.Jun-ichi MukunoNagoya UniversityProperly discontinuous isometric group actions on inhomogeneous Lorentzian manifolds...Tomoyuki HisamotoUniversity of TokyoOn the volume of graded linear series and Monge-Ampére mass...
