    Waves under time-varing delay
    (Faculty of Sciences, 2022-07-06) Lakhchine , Lynda; Lakhchine , Meriem; ATOUI , Halim
    In this work we study a transmission problem for one dimensional wave equations with nonlinear weights and under the effects of time-varying delay. Using Kato’s technique we prove existence and uniqueness of solutions and we construct a suitable Lyapunov functional to understand the asymptotic behavior of solutions.
