  Some recent studies of the AdS/CFT correspondence for condensed matter
systems involve the Fermi liquid theory as a boundary field theory. Adding
B-flux to the boundary D-branes leads in a certain limit to the noncommutative
Fermi liquid, which calls for a field theory description of its critical
behavior. As a preliminary step to more general consideration, the modification
of the Landau's Fermi liquid theory due to noncommutativity of spatial
coordinates is studied in this paper. We carry out the renormalization of
interactions at tree level and one loop in a weakly coupled fermion system in
two spatial dimensions. Channels ZS, ZS' and BCS are discussed in detail. It is
shown that while the Gaussian fixed point remains unchanged, the BCS
instability is modified due to the space non-commutativity.
