Description
Summary:<p/> <p>By using the critical point theory, we establish some existence criteria to guarantee that the nonlinear difference equation <inline-formula><graphic file="1687-1847-2010-470375-i1.gif"/></inline-formula> has at least one homoclinic solution, where <inline-formula><graphic file="1687-1847-2010-470375-i2.gif"/></inline-formula>, <inline-formula><graphic file="1687-1847-2010-470375-i3.gif"/></inline-formula> and <inline-formula><graphic file="1687-1847-2010-470375-i4.gif"/></inline-formula> is non periodic in <inline-formula><graphic file="1687-1847-2010-470375-i5.gif"/></inline-formula>. Our conditions on the nonlinear term <inline-formula><graphic file="1687-1847-2010-470375-i6.gif"/></inline-formula> are rather relaxed, and we generalize some existing results in the literature.</p>
