G-框架是经典框架概念的发展与延拓,借助算子理论和范数性质,建立了Hilbert空间中g-框架和Parseval g-框架的一些新的不等式,这些结论在结构和形式上异于已有不等式.
G-frames are natural generalizations of classical frames.By means of operator theory and properties of the norm,several new inequalities of g-frames and Parseval g-frames in Hilbert spaces which are different both in structure and form from previous ones are established.
