A conformally invariant sphere theorem in four dimensions
S. Y. A Chang, Matthew J. Gursky, Paul Yang
In this paper we provide a sharp characterization of the smooth four-dimensional sphere. The assumptions of the theorem are conformally invariant, and can be reduced to an L^2 ineq…

On the topology of conformally compact Einstein 4-manifolds
Alice Chang, Jie Qing, Paul Yang
In this paper we study the topology of conformally compact Einstein 4-manifolds. When the conformal infinity has positive Yamabe invariant and the renormalized volume is also posit…

On finiteness of Kleinian groups in general dimension
Alice Chang, Jie Qing, Paul Yang
In this paper we provide a criteria for geometric finiteness of Kleinian groups in general dimension. We formulate the concept of conformal finiteness for Kleinian groups in space…
