%0 Journal Article %T A variational approach to a singular elliptic system involving critical Sobolev-Hardy exponents and concave-convex nonlinearities %A Nemat Nyamoradi %J Mathematical Sciences %D 2013 %I %R 10.1186/2251-7456-7-11 %X This paper is concerned with a quasilinear elliptic system, which involves the Caffarelli-Kohn-Nirenberg inequality and multiple critical exponents. The existence and multiplicity results of positive solutions are obtained by variational methods. %U http://www.iaumath.com/content/7/1/11/abstract
