Query: Four-loop critical properties of polymerized membranes   We calculate four-loop order corrections to the critical exponent $\eta$ in
the two-field model of flat phase membranes. Obtained results show better
agreement with the other calculation methods and confirm the validity of the
perturbative approach to the considered problem.
