Multiple periodic solutions for a fourth-order discrete Hamiltonian system
Journal Title: Surveys in Mathematics and its Applications - Year 2010, Vol 5, Issue 0
Abstract
By means of a three critical points theorem proposed by Brezis and Nirenberg and a general version of Mountain Pass Theorem, we obtain some multiplicity results for periodic solutions of a fourth-order discrete Hamiltonian system <CENTER>Δ<SUP>4</SUP>u(t-2)+∇ F(t,u(t))=0 for all t∈ <B>Z</B>.</CENTER>
