我们展示了众所周知的经典场方程,如爱因斯坦和杨-米尔斯方程,它们是作为某些二维理论的共形不变性条件而出现的,在形式参数中扩展到二阶,可以重新表述为广义/形式毛雷尔-嘉当方程(GMC),其中微分是弦理论的 BRST 算子。我们介绍了 GMC 中存在的双线性运算,并研究了它们的性质,使我们能够找到所得方程的对称性,这些方程可以自然地与相应的爱因斯坦和杨-米尔斯方程的微分同胚和规范对称性识别。
We show how the well-known classical field equations as Einstein and Yang-Mills ones, which arise as the conformal invariance conditions of certain two-dimensional theories, expanded up to the second order in the formal parameter, can be reformulated as Generalized/formal Maurer-Cartan equations (GMC), where the differential is the BRST operator of String theory. We introduce the bilinear operations which are present in GMC, and study their properties, allowing us to find the symmetries of the resulting equations which will be naturally identified with the diffeomorphism and gauge symmetries of Einstein and Yang-Mills equations correspondingly.
