SYMPLECTIC STRUCTURES AND QUANTIZATION FOR BOSONIC STRINGS IN BRST FORMALISM

The sympletic structures for bosonic strings are given by the method restricting J^'Y to its Lagrangian submanifold and geometric quantization in BRST formulation for strings is discussed.It is found that conformal anomaly is cancelled when curvature of BRST vacuum bundle on G₀=G₀/H vanishes.
