Long Jin, Zhongkai Tao
We prove a high energy flat trace estimate for the modified resolvent of the generator of an Anosov flow. This fills a gap in the proof of the local trace formula in [Jin-Zworski '…

0-th Order Pseudo-differential Operator on the Circle
Zhongkai Tao
In this paper we consider 0-th order pseudodifferential operators on the circle. We show that inside any interval disjoint from critical values of the principal symbol, the spectru…
