In this paper, we study Hardy’s inequality in a limiting case: ∫Ω|∇u|Ndx ≥ C N(Ω)∫Ω |u(x)|N |x|N(log R |x|)Ndx for functions, whereis a bounded domain inwith. We study the attainability of the best constantin several cases. We provide sufficient conditions that assureandis attained, hereis the-dimensional ball with center the origin and radius. Also, we provide an example ofsuch thatandis not attained.
