摘要

(X,d,μ)(\mathcal{X}, d, \mu)是一个度量测度空间,LL是一个具有有界HH_\infty泛函演算且满足Davies-Gaffney估计的线性算子,Φ\Phi(0,)(0,\infty)上临界下型指数pΦ(0,1]p_\Phi^-\in(0,1]的凹函数,且对所有t(0,)t\in(0,\infty)ρ(t)t1/Φ1(t1)\rho(t)\equiv t^{-1}/\Phi^{-1}(t^{-1})。本文中,作者引入了与LL相关的广义VMO空间VMOρ,L(X){\mathrm {VMO}}_{\rho,L}({\mathcal X}),并通过帐篷空间建立了其刻画。作为应用,作者证明了(VMOρ,L(X))=BΦ,L(X)({\mathrm {VMO}}_{\rho,L}({\mathcal X}))^*=B_{\Phi,L^*}({\mathcal X}),其中LL^*表示LLL2(X)L^2({\mathcal X})中的伴随算子,BΦ,L(X)B_{\Phi,L^*}({\mathcal X})是Orlicz-Hardy空间HΦ,L(X)H_{\Phi,L^*}({\mathcal X})的Banach完备化。
