Query: Universal shape ratios for polymers grafted at a flat surface   We consider dilute non-adsorbed polymers grafted at an impenetrable surface
and compute several quantities which characterize the polymer shape: the
asphericity and the ratios of the eigenvalues of the radius-of-gyration tensor.
The results are only slightly different from those obtained for polymers in the
bulk, showing that the surface has little influence on the polymer shape.
