Existence and multiplicity of positive solutions for a class of semilinear elliptic equations involving Hardy term and Hardy–Sobolev critical exponents ✩

Existence and multiplicity of positive solutions are studied for a class of semilinear elliptic equations with Hardy term, Hardy– Sobolev critical exponents and sublinear nonlinearity by variational methods and some analysis techniques. © 2007 Elsevier Inc. All rights reserved.
