Continuous bi-g-frames for operators in Hilbert spaces

Abdelilah Karara, Mohamed Rossafi

In this paper, we will introduce the new concepts of continuous bi-g-frames and continuous K-bi-g-frame for Hilbert spaces. Then, we examine some characterizations properties with…

K-bi-g-frames in Hilbert spaces

Abdelilah Karara, Mohamed Rossafi

In this paper, we will introduce the new concept of K-bi-g-frames for Hilbert spaces. Then, we examine some characterizations with the help of a biframe operator. Finally, we inves…

K-biframes in Hilbert spaces

Abdelilah Karara, Mohamed Rossafi

In this paper, we introduce a new concept of K-biframes for Hilbert spaces. We then examine several characterizations with the assistance of a biframe operator. Moreover, we invest…
