Abstract:
We use the theory of Gabor frames to prove the boundedness of bilinear pseudodifferentialoperators on products of modulation spaces. In particular, we show that bilinearpseudodifferential operators corresponding to non-smooth symbols in the Feichtinger algebra arebounded on products of modulation spaces.
