Abstract
K-g-frame is a generalization ofg-frame. We generalize the tightg-frame toK-g-frame via atomic systems. In this paper, the definition of tightK-g-frame is put forward; equivalent characterizations and necessary conditions of tightK-g-frame are given. In particular, the necessary and sufficient condition for tightK-g-frame being tightg-frame is obtained. Finally, by means of methods and techniques of frame theory, several properties of tightK-g-frame are given.
