چکیده
|
In this paper we study the duality of bessel and g-bessel sequences in hilbert spaces. we show that a bessel sequence is an inner summand of a frame and the sum of any bessel sequence with bessel bound less than one with a parseval frame is a frame. next we develop this results to the g-frame situation.
