By the upper and lower solution method, some results on the existence of solutions of the fourth-order four-point boundary value problem on time scales are obtained. An example is also included to illustrate our results.en10.1155/2012/647235info:eu-repo/semantics/openAccessArticleWOS:000298818600001N/AQ1
