Title: A positive mass theorem for fractional GJMS operators

Abstract: In this talk, I will first give some pointwise comparison formulae for fractional Q-curvatures of different orders, which implies the comparison theorem for Green functions. Based on this, a positive mass theorem for GJMS operators of order between 2 and 4 is given. This is joint work with Huihuang Zhou.
