Boosting Differentiable Causal Discovery via Adaptive Sample Reweighting
An Zhang, Fangfu Liu, Wenchang Ma +3
Under stringent model type and variable distribution assumptions, differentiable score-based causal discovery methods learn a directed acyclic graph (DAG) from observational data b…
Flows and functional inequalities for fractional operators
Jean Dolbeault, An Zhang
This paper collects results concerning global rates and large time asymptotics of a fractional fast diffusion on the Euclidean space, which is deeply related with a family of fract…
Optimal functional inequalities for fractional operators on the sphere and applications
Jean Dolbeault, An Zhang
This paper is devoted to optimal functional inequalities for fractional Laplace operators on the sphere. Based on spectral properties, subcritical inequalities are established. The…
Restriction Theorems On Métiver Groups Associated to Joint Functional Calculus
Heping Liu, An Zhang
In this article, we get the spectral solution of operators , the joint functional calculus of the sub-Laplacian and Laplacian o…
Sharp Hardy-Littlewood-Sobolev Inequalities on Octonionic Heisenberg Group
Michael Christ, Heping Liu, An Zhang
This paper is a second one following our work [CLZ13] in series, considering sharp Hardy- Littlewood-Sobolev inequalities on groups of Heisenberg type. The first important breakthr…
Sharp Hardy-Littlewood-Sobolev Inequalities on Quaternionic Heisenberg Groups
Michael Christ, Heping Liu, An Zhang
In this paper, we got several sharp Hardy-Littlewood-Sobolev-type inequalities on quaternionic Heisenberg groups (a general form due to Folland and Stein [FS74]), using the symmetr…
