Abelization by operator equivalence in string theory

An operator is presented which transforms the “true” bosonic open-string BRST charge into the “abelized” one. The same transformation relates the transverse DDF-operators with the transverse elementary oscillators. This permits a simple realization of the light-cone gauge condition in the covariant...

Description
Summary:An operator is presented which transforms the “true” bosonic open-string BRST charge into the “abelized” one. The same transformation relates the transverse DDF-operators with the transverse elementary oscillators. This permits a simple realization of the light-cone gauge condition in the covariant Fock space. Furthermore, some light is shed upon the concept of covariant Virasoro operators. Finally, the functional representation of the abelizing operator is given, and some speculations about string field theory and string interactions are made.
