We discuss conditions for the existence of at least one positive solution to a nonlinear
second-order Sturm-Liouville-type multipoint eigenvalue problem on time scales. The
results extend previous work on both the continuous case and more general time scales,
and are based on the Guo-Krasnosel'skii fixed point theorem.

We are interested in the second-order multipoint time-scale eigenvalue problem
(t)- q(t)y(t)+h(t) f (y) = 0, t1 < t < tn, (1.1)
y t1 - p t1 y
ai y ti , y tn +p tn y
