Multipliers have been recently introduced by P. Balazs as operators
for Bessel sequences and frames in Hilbert spaces. These operators are
defined by a fixed multiplication pattern the symbol), which is inserted between
the analysis and synthesis operators [1, 2, 3]. Weighted and controlled
frames have been introduced recently to improve the numerical efficiency
of iterative algorithms for inverting the frame operator [4]. Also, g-frames
are the recent generalization of frames that include almost all of the frame
extensions.
In this paper, the concept of the controlled g-frames will be defined,
and the multiplier operator for this family of operators will be introduced.
Moreover, some of its properties will be shown
