Query: Frame Multipliers for discrete frames on Quaternionic Hilbert Spaces   In this note, following the complex theory, we examine discrete controlled
frames, discrete weighted frames and frame multipliers in a non-commutative
setting, namely in a left quaternionic Hilbert space. In particular, we show
that the controlled frames are equivalent to usual frames under certain
conditions. We also study connection between frame multipliers and weighted
frames in the same Hilbert space.
