Derivation of the gauge-invariant action for open and closed free bosonic string field theories

# metadata.dc.description.abstract[].value
The gauge-invariant actions for open and closed free bosonic string field theories are obtained from the string field equations in the conformal gauge using the cohomology operations of Banks and Peskin. For the closed-string theory no restrictions are imposed on the gauge parameters.
