摘 要: In this talk we discuss the existence of infinitely many positive conformal classes on S7 which cannot be the conformal infinity of a Poincare-Einstein metric on the ball B^8. We also discuss a sharp inequality between the Yamabe invariant of the conformal infinity and the Yamabe invariant of the interior (after a suitable compactification). The talk is based on a joint work with Matt Gursky.
