Let Ω be a C1 open bounded domain in ℝN, N ≥ 3, with (Formula presented.). We consider the following problem involving Hardy–Sobolev critical exponents: (Formula presented.), where 0 ≤ s1 < 2, 0 ≤ s2 < 2, 2 *(s2) ≠ λ ∈ ℝ, 1 ≤ p ≤ 2*(s1) - 1 and with choices of exponents and parameters corresponding to cases in which (P) has not been before investigated. We prove the existence of positive solutions, which, in some cases, are also shown to be ground states. We remark that we give a first partial answer to a question proposed by Li and Lin (Arch Ration Mech Anal 203(3):943–968, 2012). © 2015, Springer-Verlag Berlin Heidelberg.
