Webdegenerate wave equation 577 As will be shown in Section 3, it follows that R(s,w(s)) tends to 0 exponentially as s ! 1. Noting this and the fact that krwk2 L2(⌦) w is a monotone operator, we prove that the accumulation points of a solution curve {w(s)} s0 are contained in the set S = {w 2 H1 0 (⌦) krwk2 L2 w + 1 2 w = 0}.

Control and Stabilization of Degenerate Wave Equations
Websystem (P) into an augmented system by coupling the degenerate wave equation with a suitable di usion equation and we show the well-posedness of our problem by semigroup theory. In section 3, we prove lack of exponential stability by spectral analysis and by using Bessel functions. In the last section, we prove an optimal decay rate. WebJan 28, 2024 · In this work, we are concerned with the study of stabilization of one-dimensional weakly degenerate wave equation utt − (xγux)x = 0 with x ∈ (0, 1) and γ ∈ [0, 1), controlled by a fractional boundary feedback acting at x = 0.
