Long Time Solutions for Wave Maps with Large Data
نویسنده
چکیده
For 2 + 1 dimensional wave maps with S as the target, we show that for all positive numbers T0 > 0 and E0 > 0, there exist Cauchy initial data with energy at least E0, so that the solution’s life-span is at least [0, T0]. We assume neither symmetry nor closeness to harmonic maps.

Complexition and solitary wave solutions of the (2+1)-dimensional dispersive long wave equations
In this paper, the coupled dispersive (2+1)-dimensional long wave equation is studied. The traveling wave hypothesis yields complexiton solutions. Subsequently, the wave equation is studied with power law nonlinearity where the ansatz method is applied to yield solitary wave solutions. The constraint conditions for the existence of solitons naturally fall out of the derivation of the soliton so...

Abstract Wind induced wave is of great importance due to its high energy. In this study wave climate in the Gulf of Oman close to the Koohmobarak area is investigated. Wave climate study is necessary for determination of long-term analysis of wave statistics as well as climate change effects in the study area. First, wave climate is study using both measured and simulated wave data close to th...

In this paper, we obtained the 1-soliton solutions of the symmetric regularized long wave (SRLW) equation and the (3+1)-dimensional shallow water wave equations. Solitary wave ansatz method is used to carry out the integration of the equations and obtain topological soliton solutions The physical parameters in the soliton solutions are obtained as functions of the dependent coefficients. Note t...

We show that wave maps φ from two-dimensional Minkowski spaceR to hyperbolic spacesH are globally smooth in time if the initial data is smooth, conditionally on some reasonable claims concerning the local theory of such wave maps, as well as the self-similar and travelling (or stationary solutions); we will address these claims in the sequels [60], [61], [62] to this paper. Following recent wor...
