Complex structure in the Gupta-Bleuler quantization method

摘要

We examine the general conditions for the existence of the complex structure intrinsic in the Gupta-Bleuler quantization method for the specific case of mixed first and second class fermionic constraints in an arbitrary space-time dimension. The cases d = 3 and 10 are shown to be of prime importance. The explicit solution for d = 10 is presented. (C) 1998 Published by Elsevier Science B.V. [References: 24]
