摘要 研究了多重 C*-动力系统在Hilbert C*-模上表示的膨胀.设(A,α)是一个多重C*-动力系统,(π,T,E)是(A,α)的行压缩协变表示,证明了存在(π,T,E)的等距膨胀(ρ,V,F). We study the dilations of row contractive representations of multivariable C*-dynamical systems on Hilbert C*-modules. We show that if (A, α) is a multivari- able C*-dynamical system, then every covariant representation (π, T, E) of (A, α) on a Hilbert C*-module E admits an isometric dilation (ρ, V, F) on some Hilbert module F containing E as a complemented submodule.
