利用近年来在广义相对论中发展起来的技术,我们研究了没有外部源的广义GL(R,n)和GL(C,m)规范理论。特别是,铸造场方程的自旋系数形式主义和适应自然(thee形式主义)规范条件后,我们展示了如何大多数方程可以集成的情况下,真实的渐近“平坦”的解决方案。在自对偶(或反自对偶)的情况下,场方程被简化为一个赫兹型势的非线性波动方程。作为最后一点,我们展示了这个潜在的和我们的版本的Atiyah-Ward方法找到自对偶领域之间的关系。
Using techniques developed in recent years in general relativity we study the general GL(R,n) and GL(C,m) gauge theories with no external sources. In particular, after casting the field equations into the spin-coefficient formalism and adapting natural (to thee formalism) gauge conditions we show how most of the equations can be integrated in the case of real asymptotically 'flat' solutions. In the self-dual (or anti-self-dual) case the field equations are reduced to a single nonlinear wave equation for a Hertz-type potential. As a final point we show the relationship between this potential and our version of the Atiyah-Ward method of finding self-dual fields.
