Algebra-geometry of Piecewise algebraic Varieties
收藏 引用
Acta Mathematica Sinica,English Series 2012年 第10期28卷 1973-1980页
作者: Chun Gang ZHU Ren Hong WANG School of Mathematical Sciences Dalian University of Technology
algebraic variety is the most important subject in classical algebraic geometry. As the zero set of multivariate splines, the piecewise algebraic variety is a kind generalization of the classical algebraic variety. Th... 详细信息

The Minimal Measurement Number Problem in Phase Retrieval:A Review of Recent Developments
收藏 引用
Journal of Mathematical Research with Applications 2017年 第1期37卷 40-46页
作者: Zhiqiang XU LSEC Inst.Comp.Math. Academy of Mathematics and System ScienceChinese Academy of Sciences University of Chinese Academy of Sciences
Phase retrieval is to recover the signals from phaseless measurements which is raised in many areas. A fundamental problem in phase retrieval is to determine the minimal measurement number m so that one can recover d-... 详细信息
