Abstract:

In this talk, We use the potential and spectral estimates developed by Hang–Yang and our observation, made jointly with Xu, on the positivity of Q-curvature, to study the relationship between, on the one hand, the existence of metrics with both positive scalar curvature and positive Q-curvature and, on the other hand, the positivity of conformally invariant quantities.
