摘要
类似于Campanato空间理论,本文对具有以下连续模的函数类给出了一局部积分刻画:u(x)-u(y)≤Cx-yα(logx-y-1∨1)β,x,y∈Ω,其中C>0,Ω为Rd中一正则区域,α∈(0,1],β∈[0,1].
Similar to the Campanato spaces, in this note we give a local integral characterization to the functions which have continuous modulus: |u(x) - u(y)| ≤C |,x - y | (log |x - y|^ -1 V 1)β,x, y ∈Ω, where C 2〉0,Ω is a regular domain in Rd, and a E (0,1], β [0,1].
