Abstract:In this paper, some Gronwall-Bellman type nonlinear delay integral inequalities on time scales are established, which provide a handy tool in deriving boundedness of solutions of certain delay dynamic equations on time scales. Our results generalize some of the main results in Lipovan (2006) [1], Pachpatte (2000) [2], Ferreira and Torres (2009) [3], Zhang and Meng (2008) [4], Cheung and Ren (2006) [5], Kim (2009) [6], and some of our results unify continuous and discrete analysis in the literature.
“…Liang et al extend the study of Lazarević et al and Luo et al to study a second order–delayed system based on the notation of delayed matrix cosine/sine of a polynomial of degree. For more recent contributions, we refer the reader to several previous studies . However, to our best knowledge, finite‐time stability of oscillating systems with 2 delays have not been studied extensively.…”

In this paper, we study finite‐time stability of an oscillating system with 2 delays. To derive a bounded of state vector, we use a representation of explicit solution involving 2‐delayed matrix polynomial of 2 indices after deriving some fundamental estimates for such delayed matrix polynomial of 2 indices. A sufficient condition is given. Finally, an example is given to demonstrate the application of the main result.

“…In [13], Hilger initiated the theory of time scale trying to treat continuous and discrete analysis in a consistent way. Since then, the theory of time scale has received a lot of attention in recent years, and various investigations have been done by many authors [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. Among these investigations, some authors have taken research in oscillation of dynamic equations on time scales (see [29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46] and the references therein).…”
In this paper, we investigate oscillatory and asymptotic properties for a class of fractional order dynamic equations on time scales, where the fractional derivative is defined in the sense of the conformable fractional derivative. Based on the properties of conformable fractional differential and integral, some new oscillatory and asymptotic criteria are established. Applications of the established results show that they can be used to research oscillation for fractional order equations in various time scales such as fractional order differential equations, fractional order difference equations, and so on.
“…The travelling waves solution, peaked solitary wave solutions for equation (1) with g(u) = au m + ku and some α, m, γ were showed in [28,27] and references therein. More related work in this fields can be found in [23,21,19,22,29,30,31,32,25].…”
It was showed that the generalized Camassa-Holm equation possible development of singularities in finite time, and beyond the occurrence of wave breaking which exists either global conservative or dissipative solutions. In present paper, we will further investigate the uniqueness of global conservative solutions to it based on the characteristics. From a given conservative solution u = u(t, x), an equation is introduced to single out a unique characteristic curve through each initial point. By analyzing the evolution of the quantities u and v = 2 arctan ux along each characteristic, it is obtained that the Cauchy problem with general initial data u 0 ∈ H 1 (R) has a unique global conservative solution.
