Agarwal, R.P.; O'Regan, D.
Triple solutions to boundary value problems on time scales. (English)
[J] Appl. Math. Lett. 13, No.4, 7-11 (2000). ISSN 0893-9659

Using the Leggett-Williams fixed-point theorem, three nonnegative solutions are proved to nonlinear differential equations on time scales. The obtained result is new for differential equations as well as discrete particular cases.
