Kloosterman sums with multiplicative coefficients被引量:1
《Science China Mathematics》2016年第4期653-660,共8页GONG Ke JIA ChaoHua 
supported by National Natural Science Foundation of China(Grant Nos.11201117 and 11126150),supported by National Natural Science Foundation of China(Grant Nos.11371344 and 11321101);National Key Basic Research Program of China(Grant No.2013CB834202)
Let f(n)be a multiplicative function satisfying |f(n)|≤1,q(≤N^2)be a positive integer and a be an integer with(a,q)= 1.In this paper,we shall prove that ∑n≤N(n,q)=1f(n)e(an/q)■(1/2)(τ(q)/q)N loglog(6N)+ q^(1/4+...

Preconditioned Iterative Methods for Algebraic Systems from Multiplicative Half-Quadratic Regularization Image Restorations被引量:1
《Numerical Mathematics(Theory,Methods and Applications)》2010年第4期461-474,共14页Michael K.Ng

A general additive-multiplicative rates model for recurrent event data被引量:5
《Science China Mathematics》2009年第10期2257-2265,共9页DAI JiaJia SUN LiuQuan YANG ZhenHai 
supported by National Natural Science Foundation of China (Grant Nos. 10571169, 10731010);National Basic Research Program of China (Grant No. 2007CB814902)
In this article, we propose a general additive-multiplicative rates model for recurrent event data. The proposed model includes the additive rates and multiplicative rates models as special cases. For the inference on...
