【摘要】 如果一个酉系统有完全的游荡向量,那么它的框架向量可以参数化.这有利于研究每种类型的框架向量和它们的相互关系.该文主要给出了一个酉系统的框架向量的参数化结果,无论这个酉系统是否有完全的游荡向量,其应用是:给出了两个框架向量弱相交、相交和强相交的等价条件.更多还原

【Abstract】 If an unitary system has a complete wandering vector,its frame vectors can be paramerterized.It is useful to research the qualities of every kind of frame vectors and their mutual relations.In this paper,the parameterization of frame vectors of an unitary system which perhaps has no complete vector is given.As an application,the equivalent conditions of weak disjointness,disjointness and strong disjointness respectively are given.更多还原
