چكيده فارسي :
In this note, we give a review of Bessel multipliers and generalized Bessel multipliers in Hilbert
spaces and then some necessary or sufficient conditions for the invertibility of such operators are
investigated. We show that the invertibility of multipliers depends on the properties of the
.underlying sequences
