Abstract:A generalization of the Camassa-Holm equation, a model for shallow water waves, is investigated. Using the pseudoparabolic regularization technique, its local well-posedness in Sobolev space H s (R) with s > 3 2 is established via a limiting procedure. In addition, a sufficient condition for the existence of weak solutions of the equation in lower order Sobolev space H s with 1 < s 3 2 is developed.
“…which contradicts the assumption of the maximal existence time < +∞. Conversely, using Sobolev's embedding theorem → ∞ ( > 1/2), we derive that if condition (9) in Theorem 2 holds, the corresponding solution blows up in finite time, which completes the proof of Theorem 2.…”

“…Li and Olver [8] not only obtained the local posedness but also gave the conditions which could lead to some solutions blowing up in finite time in Sobolev space with > 3/2. For other methods to establish the local well-posedness and global existence of solutions to the Camassa-Holm equation or other shallow water models, the reader is referred to [9][10][11][12][13][14][15][16][17][18] and the references therein.…”

“…Motivated by the work in [9,21,23,27,33,[35][36][37][38], we study the weakly dissipative Camassa-Holm system (1). We note that the Cauchy problem of system (1) in Besov spaces has not been discussed yet.…”
The weakly dissipative 2-component Camassa-Holm system is considered. A local well-posedness for the system in Besov spaces is established by using the Littlewood-Paley theory and a priori estimates for the solutions of transport equation. The wave-breaking mechanisms and the exact blow-up rate of strong solutions to the system are presented. Moreover, a global existence result for strong solutions is derived.

“…Coclite et al [6] used the analysis in [5] and established the existence of global weak solutions for a generalized hyperelastic rod wave equation (or a generalized Camassa-Holm equation); namely, = = 0 in (1). For the global or local solutions of the Camassa-Holm equation and other partial differential equations, the reader is referred to [7][8][9][10][11][12] and the references therein.…”
Assuming that the initial valuev0(x)belongs to the spaceH1(R), we prove the existence of global weak solutions for a weakly dissipative hyperelastic rod wave equation in the spaceC([0,∞)×R)⋂L∞([0,∞);H1(R)). The limit of the viscous approximation for the equation is used to establish the existence.
In this paper, we mainly revisit a weakly dissipative periodic two‐component
‐family system. Considering the dissipative effect, the local well‐posedness is first obtained for the system by applying the Kato's semigroup theory. We then utilize the characteristics line method to get one blow‐up criterion with the dispersive parameter
. Finally, the other blow‐up criterion is derived with regard as considering the odevity of initial data by using energy method. When the parameters
belong to suitable range, our obtained results supplement the corresponding blow‐up criteria, which was derived by Liu and Yin (Nonlinear Analysis: Real World Applications 12 (2011) 3608–3620).
