Abstract

The closed and open bosonic strings are quantized in the Tomonaga-Schwinger-Dirac (TSD) formalism. This leads to a gauge-invariant second-quantized free string field theory. The worldsheet parameters are dynamical variables which, in the quantum theory, are represented by anticommuting operators. This TSD quantization is seen to be formally identical to the BRST quantization and provides a geometrical interpretation of the anticommuting BRST ghosts as quantized worldsheet parameters.
