Stability and boundedness to certain differential equations of fourth order with multiple delays

In this paper, we give sufficient conditions to guarantee the asymptotic stability and bounded ness of solutions to a kind of fourth-order functional differential equations with multiple delays. By using the Lyapunov-Krasovskii functional approach, we establish two new results on the stability and bounded ness of solutions, which include and improve some related results in the literature. © 2014, University of Nis.
