研究了具有占优混合光滑性的Besovand TriebelLizorkin型空间的限制S r̄p,qb(Ω)和S r̄p,qf(Ω),其中Ω表示矩形区域.对于一般的参数范围(r̄∈Rd,p,q>0),我们利用Peetre型极大函数和局部平均给出了S r̄p,qb(Ω)和S r̄p,qf(Ω)的内蕴特征.该方法基于Rychkov[9]的一篇论文,其中处理了Lipschitz域的各向同性问题,以及Vybíral[22]和Bazarkhanov[2]给出的刻画。
We study the restrictions S r̄ p,qB(Ω) and S r̄ p,qF (Ω) of the Besovand TriebelLizorkin type spaces with dominating mixed smoothness, where Ω denotes a rectangular domain. For a general range of parameters (r̄ ∈ Rd, p, q > 0) we give explicit intrinsic characterizations of S r̄ p,qB(Ω) and S r̄ p,qF (Ω) in terms of Peetre type maximal functions and local means. The approach is based on a paper by Rychkov [9], where the isotropic problem for Lipschitz domains is treated, as well as on characterizations given by Vybíral [22] and Bazarkhanov [2].
