Controlled \(K\)-g-frames in Hilbert spaces
\(K\)-frames, \(K\)-g-frames, controlled frames and controlled g-frames are four important concepts related to frame theory in Hilbert spaces which have been introduced and widely studied recently. Now, the authors of the present paper consider controlled \(K\)-g-frames in Hilbert spaces and get some properties of them. Especially some results about the equivalence of controlled \(K\)-g-frames with \(K\)-g-frames and constructions of controlled \(K\)-g-frames are obtained.
