New analytical results on anisotropic membranes

We report on recent progress in understanding the tubular phase of self-avo iding anisotropic membranes. After an introduction to the problem, we sketc h the renormalization group arguments and symmetry considerations that lead us to the most plausible fixed point structure of the model. We then emplo y an E-expansion about the upper critical dimension to extrapolate to the p hysical interesting 3-dimensional case. The results are nu = 0.62 for the F lory exponent and zeta = 0.80 for the roughness exponent. Finally we commen t on the importance that numerical tests may have to test these predictions .
