A.Kamyabi GolDepartment of Mathematics, Ferdowsi University of MashhadR.Raisi TousiDepartment of Mathematics, Ferdowsi University of MashhadJournal Article20121227In this note, we aim to show that several known generalizations of frames are equivalent to the continuous frame defined by Ali et al. in 1993. Indeed, it is shown that these generalizations can be considered as an operator between two Hilbert spaces.http://bims.iranjournals.ir/article_550_a9b4d08783a83fc5fff14349bb6bf7bc.pdf
