Isoperimetric Inequalities and Imbedding Theorems in Irregular Domains

Abstract

The paper proves several weighted imbedding theorems for domains with fractal boundaries.The weights considered are distances to the boundary to certain powers, and the domains are so-called s-John domains.The paper also proves, in the general setting, that the existence of an imbedding implies compactness of the imbedding for lower exponents.Moreover, following Maz'ya, the paper reformulates the imbedding theorems in the language of local isoperimetric and capacity estimates.holds if and only if a version of the isoperimetric inequality involving exponent q is
