Eigenvalue problems for singular multi-point dynamic equations on time scales

open access: yesElectronic Journal of Differential Equations, 2017
In this article, we study a singular multi-point dynamic eigenvalue problem on time scales. We find existence of positive solutions by constructing the Green's function and studying its positivity eigenvalue intervals. Two examples are given to

Positive solutions of boundary value problem for singular positone and semi-positone third-order difference equations

open access: yesAdvances in Difference Equations, 2011
This article studies the boundary value problems for the third-order nonlinear singular difference equations Δ 3 u ( i - 2 ) + λ a ( i ) f ( i , u ( i ) ) = 0 , i ∈ [ 2 , T + 2 ] , satisfying five ...
