HIGHLIGHTS

• who: J.-P. Antoine from the (UNIVERSITY) have published the paper: Lower Semi-frames, Frames, and Metric Operators, in the Journal: (JOURNAL)
• what: It turns out that most results from_[21,22] can be extended to the continuous case and that is one of the aims of this present paper. In Sect 4, the authors investigate the various (semi)-frames generated by a lower semi-frame.
