Query: Nonlocal characterizations of variable exponent Sobolev spaces   We obtain some nonlocal characterizations for a class of variable exponent
Sobolev spaces arising in nonlinear elasticity theory and in the theory of
electrorheological fluids. We also get a singular limit formula extending
Nguyen results to the anisotropic case.
