چکیده
|
G-frames in hilbert spaces are a redundant set of operators which yield a representation for each vector in the space. in this paper we investigate the connection between g-frames, g-orthonormal bases and g-riesz bases. we show that a family of bounded operators is a g-bessel sequences if and only if the gram matrix associated to its denes a bounded operator.
