Abstract: | The string model proposed by Polyakov is investigated as a two-dimensional field theory with higher-order derivatives. We reduce the model lagrangian to a simple useful form and achieve the BRST quantization. We show the nilpotence of the BRST charge under certain conditions, and discuss the unitarity of the theory. |
