KPZ limit for one-dimensional weakly asymmetric Ginzburg-Landau model was studied by Diehl-Gubinelli-Perkowski in a setting of martingale (energy) solution. Our goal is to apply a path-wise approach b...
广义Stein无偏风险估计与地球物理反问题正则化参数求取
广义Stein无偏风险估计 反问题 正则化参数 反褶积
2019/3/21
地球物理反演是获取地球信息的重要手段，其求解具有严重的不适定性.为获得稳定的反问题结果，通常需要在目标泛函中加入正则化约束项.正确地估计正则化参数一直是地球物理反问题中的难点.目前存在的选取方法需要根据大量的试验来确定正则化参数，工作量十分巨大，并且存在很大的经验性，很难得到最优的正则化参数.针对这个问题，本文提出了一种基于广义Stein无偏风险估计的正则化参数求取方法.该方法的具体思路是通过求解...

Abstract: In this paper we provide sufficient conditions for the graphs of holomorphic mappings on compact sets in complex manifolds to have Stein neighborhoods. We show that under these conditions th...
Improved bounds for Stein's square functions
Square functions Bochner–Riesz means Wave and Schr¨odinger semigroup
2011/1/20
We prove a weighted norm inequality for the maximal Bochner–Riesz operator and the associated square-function. This yields new Lp(Rd) bounds on classes of radial Fourier multipliers for p 2 + 4/d wi...

石泰安(Rolf Alfred Stein，1911-1999) ，法国著名的中国学家、藏学家，1911年6月13日诞生于德国施韦茨的一个犹太家庭。在柏林大学获得汉语文凭以后，1933年为躲避法西斯当局对犹太人的迫害而离开德国，移居法国。在巴黎，他进入东方语言学院（Ecole Nationale des Langues Orientales Vivantes）学习汉语和日语，接着又在第五组高等研究...
Using Eliashberg's theorem about Stein fillings of S3 we prove that a section of a Lefschetz fibration over S2 has nonnegative square. This observation, in particular, implies that the identity elemen...
In the following we show that a Stein filling S of the 3-torus T3 is homeomorphic to D2 \times T2. In the proof we also show that if S is Stein and \partial S is diffeomorphic to the Seifert fibered 3...
