Eigenvalue Comparisons for Differential Equations on a Measure Chain
MetadataShow full metadata
The theory of u0-positive operators with respect to a cone in a Banach space is applied to eigenvalue problems associated with the second order Δ-differential equation (often referred to as a differential equation on a measure chain) given by yΔΔ (t) + λp(t)y(σ(t)) = 0, t ∈ [0,1] satisfying the boundary conditions y(0) = 0 = y(σ2(1)). The existence of a smallest positive eigenvalue is proven and then a theorem is established comparing the smallest positive eigenvalues for two problems of this type.
