Multiple Nonnegative Solutions for a Class of Fourth-Order BVPs Via a New Topological Approach

نویسندگان

چکیده

In this paper, we study a class of fourth-order boundary value problems with integral conditions. The nonlinearity may have time-singularity and change sign. Moreover, it satisfies general polynomial growth A new topological approach is applied to prove the existence at least two nonnegative classical solutions. An example application illustrates result.

MULTIPLE NONNEGATIVE SOLUTIONS FOR BVPs OF FOURTH-ORDER DIFFERENCE EQUATIONS

First, existence criteria for at least three nonnegative solutions to the following boundary value problem of fourth-order difference equation Δ4x(t− 2) = a(t) f (x(t)), t ∈ [2,T], x(0)= x(T +2)=0, Δ2x(0)=Δ2x(T)=0 are established by using the well-known LeggettWilliams fixed point theorem, and then, for arbitrary positive integerm, existence results for at least 2m− 1 nonnegative solutions are ...

Multiple Periodic Solutions for a Fourth-order Discrete Hamiltonian System

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 ∆u(t− 2) +∇F (t, u(t)) = 0, for all t ∈ Z.
