Exponential decay for semilinear wave equations with viscoelastic damping and delay feedback (2009.07777v1)
Published 16 Sep 2020 in math.AP
Abstract: In this paper we study a class of semilinear wave type equations with viscoelastic damping and delay feedback with time variable coefficient. By combining semigroup arguments, careful energy estimates and an iterative approach we are able to prove, under suitable assumptions, a well-posedness result and an exponential decay estimate for solutions corresponding to small initial data. This extends and concludes the analysis initiated in [16] and then developed in [13, 17].
