Eigenvalue Problem For Fractional Difference Equation With Nonlocal Conditions
JOURNAL OF APPLIED ANALYSIS AND COMPUTATION(2021)
摘要
In this work, we investigate a class of boundary value problem for fractional difference equation with nonlocal conditions{Delta(nu)u(t) + lambda f(t + nu - 1, u(t + nu - 1)) = 0, t is an element of N-0(b+1),u(nu - 2) = h(u), Delta u(nu + b) = g(u),where 1 < nu <= 2 is a real number, f : N-nu-1(nu+b) x R -> (0, +infinity) is a continuous function, g, h are given functionals, b >= 2 is an integer, lambda > 0 is a parameter. By upper and lower solutions method, we can present the existence result of positive solutions. The eigenvalue intervals to this problem are studied by the properties of the Green function and Guo-Krasnosel'skii fixed point theorem in cones.
