Discrete bilinear operators and commutators

Abstract: We discuss boundedness properties of certain classes of discrete bilinear operators that are similar to those of the continuous bilinear pseudodifferential operators with symbols in the H\"ormander classes $BS^{\omega}_{1, 0}$. In particular, we investigate their relation to discrete analogues of the bilinear Calder\'on-Zygmund singular integral operators and show compactness of their commutators.
