On the Arbitrariness of the General Solution ofan
نویسنده
چکیده
The relationship between the strength of a diierential equation as introduced by Einstein, its Cartan characters and its Hilbert polynomial is studied. Using the framework of formal theory previous results are extended to non-linear equations of arbitrary order and to over-determined systems. The problem of computing the number of arbitrary functions in the general solution is treated. Finally, the eeect of gauge symmetries is considered.

Arbitrariness of the General Solution and Symmetries
The computation of the number of arbitrary functions in the general solution is brieey reviewed. The results are used to study normal systems and their symmetry reduction. We discuss the treatment of gauge systems, especially the analysis of gauge xing conditions. As examples the Yang-Mills equations with the Lorentz gauge and Einstein's vacuum eld equations with harmonic coordinates are consid...

متن کاملOn the Exact Solution for Nonlinear Partial Differential Equations
In this study, we aim to construct a traveling wave solution for nonlinear partial differential equations. In this regards, a cosine-function method is used to find and generate the exact solutions for three different types of nonlinear partial differential equations such as general regularized long wave equation (GRLW), general Korteweg-de Vries equation (GKDV) and general equal width wave equ...
