| چکیده مقاله |
| In this note, we define the concept of controlled K-Riesz bases in Hilbert spaces and then we give a characterization of them. We also show that under some conditions, every controlled K-Riesz basis is a controlled K-frame. In the sequel, by reminding the concept of controlled K-dual sequences, we show that every controlled K-Riesz basis has a unique controlled K-dual. Finally, we characterize all controlled K-duals of a controlled K-Riesz basis. |
