RETRACTED: Multiple nodal solutions for quasilinear elliptic problems involving Hardy–Sobolev critical exponents in symmetric domain

This article has been retracted at the request of the Editor-in-Chief and author. Please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).Reason: In the proof of Lemma 2.8 in this paper, the authors mistakenly claimed to have obtained uλ in Mτλ. However, uλ=vλ(·−y) does not belong to uλ in Mτλ, making the statement uλ in Mτλ false. The same error occurs in the proof of Lemma 4.6. The failure of both Lemmas 2.8 and 4.6 makes Theorem 1.1 and 1.2 invalid.The authors sincerely apologize for the errors.
