Sharp endpoint estimates of quantum Schrödinger groups
Zhijie Fan, Guixiang Hong, Liang Wang
In this article, we establish sharp endpoint estimates of Schrödinger groups on general measure spaces which may not be equipped with good metrics but admit submarkovian semi…

Quantitative weighted estimates for rough singular integrals on homogeneous groups
Zhijie Fan, Ji Li
In this paper, we study weighted boundedness ( and a Muckenhoupt weight) of singular integrals with homogeneous convolution kernel on an a…

Weak type bounds for Schrödinger groups via generalized Gaussian estimates
Zhijie Fan
Let be a non-negative self-adjoint operator acting on , where is a space of homogeneous type with a dimension . Suppose that the heat operator satisfie…
