Several existence theorems of twin positive solutions are established for a
nonlinear -point boundary value problem of third-order -Laplacian dynamic equations on time
scales by using a fixed point theorem. We present two theorems and four corollaries which generalize
the results of related literature. As an application, an example to demonstrate our results is given.
The obtained conditions are different from some known results.
