The Cauchy problem of the Klein-Gordon-Zakharov equation in three dimensional space {utt-?u + u =-nu,(x, t) ∈ R3× R+,ntt-?n= ?|u|2,(x, t) ∈ R3× R+,u(x, 0
Let α∈ (0, n-1/2) and Tα be the Bochner-Riesz operator of order α. In thispaper, for n=2 and n≥3, the compactness on Lebesgue spaces and Morrey spaces arecon
The empirical likelihood is used to propose a new class of quantile estimators in the presence of some auxiliary information under positively associated samples
In this paper, we investigate the factor properties and gap sequence of the Tribonacci sequence, the fixed point of the substitution σ(a, b, c) =(ab, ac, a). Let
