Hilbert空间Cd中框架的若干性质
SOME PROPERTIES OF FRAMES FOR THE HILBERT SPACE Cd
摘要
Abstract
Some important properties of frames for the Hilbert space Cd are discussed. Denote by Fd(A,B) the set of all frames for Cd with frame below bound A and upper bound B, denote by Md(A,B) the set of all d by d positive definite matrices C such that A≤ET(C) : = (C&,&)≤B for all unit vectors &€Cd. Some properties of Md(A,B) and Fd(A,B) are given, and relationships between them are obtained.关键词
