A note on semidefinite programming relaxations for polynomial optimization over a single sphere被引量：7
《Science China Mathematics》2016年第8期1543-1560,共18页HU Jiang JIANG Bo LIU Xin WEN ZaiWen 
supported by National Natural Science Foundation of China (Grant Nos. 11401364, 11322109, 11331012, 11471325 and 11461161005);the National High Technology Research and Development Program of China (863 Program) (Grant No. 2013AA122902);the National Center for Mathematics and Interdisciplinary Sciences, Chinese Academy of Sciences;National Basic Research Program of China (973 Program) (Grant No. 2015CB856002)
We study two instances of polynomial optimization problem over a single sphere. The first problem is to compute the best rank-1 tensor approximation. We show the equivalence between two recent semidefinite relaxations...

Compressed sensing of superimposed chirps with adaptive dictionary refinement被引量：1
《Science China(Information Sciences)》2013年第12期167-181,共15页HU Lei ZHOU JianXiong SHI ZhiGuang FU Qiang 
supported by National Natural Science Foundation of China(Grant Nos.60972113,61101179)
The compressed sensing （CS） theory shows that accurate signal reconstruction depends on presetting an appropriate signal sparsifying dictionary. For CS of superimposed chirps, this dictionary is typically taken to b...

SOME RESULTS ABOUT BEST COAPPROXIMATION IN L^P(S, X)
《Analysis in Theory and Applications》2010年第1期69-75,共7页M. R. Haddadi N. Hejazjpoor H. Mazaheri 
As a counterpart to best approximation in normed linear spaces, the best coapproximation was introduced by Francbetti and Furl. In this paper, we shall consider the relation between coproximinality M in X and L^P（S,M...

Calculations of state-selective differential cross sections for charge transfer in collisions between O^(3+) and H_2
《Chinese Physics B》2008年第8期2890-2896,共7页迟宝倩 刘玲 王建国 
supported by the National Natural Science Foundation of China (Grant Nos 10574018 and 10574020)
The non-dissociative charge-transfer processes in collisions between O^3＋ and H2 are investigated by using the quantum-mechanical molecular-orbital coupled-channel （QMOCC） method. The adiabatic potentials and radia...

《Analysis in Theory and Applications》2006年第2期141-145,共5页H.Mazaheri 
The concepts of quasi-Chebyshev and weakly-Chebyshev and σ-Chebyshev were defined [3 - 7], andas a counterpart to best approximation in normed linear spaces, best coapprozimation was introduced by Franchetti and Furi...
