Controlled frames have been introduced to improve the numerical efficiency of iterative algorithms for inverting the frame operator. In this paper, we introduce the concept of controlled K-g-frames, and make controlled g-frames as a special case of that. Then, we discuss characterizations of controlled K-g-frames, hash out equivalent conditions of them and show that controlled K-g-frames are equivalent to K-g-frames under some conditions. Finally, we propose several methods to construct… CONTINUE READING
