By means of the Ekeland¡¯s variational principle and the Mountain Pass Theorem, we obtain that there is at least a nontrivial solution for the subcritical system. Then we prove that there are at least two different solutions for the critical system. %K Existence of Solutions %K Klein-Gordon-Maxwell Equations %K Hardy-Sobolev Critical Exponents %U http://www.oalib.com/paper/6760167
