【摘要】 本文在谐和条件下对引力场进行正则量子化.我们把引力场分解成横场和两种自对易场,研究了自对易场 X_μ的运动方程和自对易场对物理态之间的 S矩阵元的贡献,从而求得作用量中的规范补偿项.我们的结果和用轨道积分方法求得的相同,但是我们的方法可以克服 Gribov 规范不确定性的困难.更多还原

【Abstract】 The gravitational field is quantized within the canonical formalism under theharmonic gauge condition.The gravitational field is decomposed into transversalfields and self-commuting fields.The equation of motion of the self-commuting fieldX_μ is derived,and the contributions of self-commuting fields to physical S-matrixelements are investigated.Then the gauge compensating term of the effective actionis obtained.The result is in agreement with that obtained by the path integral method,but with our method the difficulty of the Gribov gauge ambiguity can be overcome.更多还原
