Denote points in ℝk × ℝN - k as pairs ξ = (x,y), and assume 2 ≤ k < N. In this paper, we study the problem [Formula: see text] where [Formula: see text] and [Formula: see text], the Hardy constant. Our results are the following: (i) Let [Formula: see text]. Then there exists at least an entire cylindrically symmetric solution. (ii) Let [Formula: see text] and λ ≥ 0. Then any solution v ∈ Lp(ℝN;|x|-bdξ) is cylindrically symmetric. (iii) Let [Formula: see text] and [Formula: see text]. Then ground state solutions are not cylindrically symmetric, and therefore there exist at least two distinct entire solutions. We prove also similar results for the degenerate problem [Formula: see text] namely, for the Euler–Lagrange equations of the Maz'ya inequality with cylindrical weights.
