Decay Properties for Solutions of Fifth Order Nonlinear Dispersive Equations
We consider the initial value problem associated to a large class of fifth order nonlinear dispersive equations. This class includes several models arising in the study of different physical phenomena. Our aim is to establish special (space) decay properties of solutions to these systems. These properties complement previous unique continuation results and in some case, show that they are optim...
متن کاملStability of Compacton Solutions of Fifth-Order Nonlinear Dispersive Equations
We consider fifth-order nonlinear dispersive K(m,n, p) type equations to study the effect of nonlinear dispersion. Using simple scaling arguments we show, how, instead of the conventional solitary waves like solitons, the interaction of the nonlinear dispersion with nonlinear convection generates compactons the compact solitary waves free of exponential tails. This interaction also generates ma...
متن کاملNew explicit traveling wave solutions for three nonlinear evolution equations
Abstract: In this paper, we demonstrate the effectiveness of the (G ′ G )-expansion method by seeking more exact solutions of the SRLW equation, the (2+1) dimensional PKP equation and the (3+1) dimensional potential-YTSF equation. By the method, the two nonlinear evolution equations are separately reduced to non-linear ordinary differential equations (ODE) by using a simple transformation. As a...
متن کاملShock Waves and Compactons for Fifth-order Nonlinear Dispersion Equations
The following question is posed: to justify that the standing shock wave S−(x) = −signx = − { −1 for x < 0, 1 for x > 0, is a correct “entropy” solution of fifth-order nonlinear dispersion equations (NDEs), ut = −(uux)xxxx and ut = −(uuxxxx)x in R × R+. These two quasilinear degenerate PDEs are chosen as typical representatives, so other similar (2m+ 1)th-order NDEs with no divergence structure...
متن کاملFifth-order iterative methods for solving nonlinear equations
In this paper, we suggest and analyze a new two-step iterative method for solving nonlinear equation f(x) = 0 by rewriting the given nonlinear equation as a coupled system of equations and using the Taylor series. It is shown that this new iterative method is of fifth-order. Several examples are given to illustrate its performance and efficiency. Comparison with other methods is also given. Thi...
