Logarithmic gradient estimate and Universal bounds for semilinear elliptic equations revisited [PDF]
arXiv, 2023 We use the Bernstein method to provide logarithmic gradient estimates and universal boundedness estimates for semilinear elliptic equations that satisfy the subcritical index condition. Our estimates are applicable to equations on Riemannian manifolds with (Bakry-\'{E}mery) Ricci curvature that is bounded below, and they are original for many concrete ...

Automatic Debiased Machine Learning of Causal and Structural Effects
, 2020 Many causal and structural effects depend on regressions. Examples include average treatment effects, policy effects, average derivatives, regression decompositions, economic average equivalent variation, and parameters of economic structural models. The

Adjusted empirical likelihood with high-order precision [PDF]
, 2010 Empirical likelihood is a popular nonparametric or semi-parametric statistical method with many nice statistical properties. Yet when the sample size is small, or the dimension of the accompanying estimating function is high, the application of the ...

Estimating Unknown Time-Varying Parameters in Uncertain Differential Equation [PDF]
arXiv, 2021 Uncertain differential equations have a wide range of applications. How to obtain estimated values of unknown parameters in uncertain differential equations through observations has always been a subject of concern and research, many methods have been developed to estimate unknown parameters. However, these parameters are constants.

${W}^{2,p}$ Estimates for Elliptic Equations on $C^{1,α}$ Domains [PDF]
arXiv, 2022 In this paper, a new method is represented to investigate boundary $W^{2,p}$ estimates for elliptic equations, which is, roughly speaking, to derive boundary $W^{2,p}$ estimates from interior $W^{2,p}$ estimates by Whitney decomposition. Using it, $W^{2,p}$ estimates on $C^{1,\alpha}$ domains are obtained for nondivergence form linear elliptic ...

Strichartz estimates for Maxwell equations in media: The partially anisotropic case [PDF]
arXiv, 2021 We prove Strichartz estimates for solutions to Maxwell equations in three dimensions with rough permittivities, which have less than three different eigenvalues. To this end, Maxwell equations are conjugated to half-wave equations in phase space. We use the Strichartz estimates in a known combination with energy estimates to show the new well-posedness
