| Abstract: | Choosing the space Cg as the phase space of the solutions for the systems with infinite delay,the exponentially asymptotic stability and the boundedness of the solutions,for a king of neutral functional differential equations with infinite delay,are investigated.By using of Bellman inequality and the comparison theorem,under some suitable conditions,the new result that the g-exponentially asymptotic stability implies the g-boundedness of the solutions is obtained.The obtained results are different from the ... |
