| dc.description.abstract | In this work, two coupled systems for two wave equations have been considered; In the first system we have made the past history in two equations, however in the second system we have considered the past history only in the first equation. Under some hypotheses in given data we have showed the global existence and uniqueness of solutions of two systems by using the semigroup theory. After, we have proved the exponential decay for the first system and for the second system we have obtained the lack exponential decay of solutions, consequently we have got the optimal polynomial decay. | en_US |
