We get a result that shows the existence of infinitely many solutions for a class of the elliptic systems involving subcritical Sobolev exponents nonlinear terms with even functionals on the bounded domain with smooth boundary. We get this result by variational method and critical point theory induced from invariant subspaces and invariant functional.
Keywords: elliptic system, deformation lemma, $(P.S.)^{*}$ condition, subcritical Sobolev exponents, variational method, critical point theory, invariant functional, invariant subspaces
