In this paper we deal with a class of non-differentiable functionals defined on a real reflexive Banach space X and depending on a real parameter of the form <InlineEquation ID="IEq1"> <EquationSource Format="TEX">$${\mathcal{E}_\lambda(u)=L(u)-(J_1\circ T)(u)-\lambda (J_2\circ S)(u)}$$</EquationSource> </InlineEquation>, where <InlineEquation ID="IEq2"> <EquationSource Format="TEX">$${L:X \rightarrow \mathbb R}$$</EquationSource> </InlineEquation> is a sequentially...</equationsource></inlineequation></equationsource></inlineequation>
