“…To study the stabilization of the system (1), as already mentioned, we will use the backstepping method. We focus on the construction of an appropriate Fredholm transformation, in the spirit of [11], which has emerged as an alternative to the Volterra transformation during the last years (see also [12,13,28,16,17,15]). Let us emphasize that our main stabilization result can be obtained from the abstract theorem given in [1,Theorem 1.6], but the backstepping method has some additional advantages (see [16, Remark 2]) that make relevant the present study.…”
