摘要 本文给出了赋以混合范数的各向异性多元Besov类BPθr(Rd)的一个表现定理, 利用此表现定理,证明了它在不同度量下的一个嵌入定理BPθr(Rd)→Bqθr'(Rd),其中 1≤P≤q≤∞,r'=(1-∑jd=1(1/pj-1/qj)1/rj)r. In this paper, we establish a representation theorem on anisotropic Besov r class with mixed norm Bpθ^r(R^d). Using this theorem, we prove an embedding theorem on the Besov class with mixed norm in different metrics: Bpθ^r(R^d)→Bqθ^r′(R^d), where 1≤p≤q≤∞,r′=(1-∑j=1^d(1/pj-1/qj)1/rj)r.
