Symmetries in Bosonization
  Two-dimensional quantum field theories are important in many problems in physics because they contain exact symmetries and are often completely integrable. We demonstrate the power of bosonization in elucidating the structure of a multi-component fermion theory with chiral and internal symmetries. Many remarkable features and quantum symmetries in such a system are most readily uncovered in the bosonized form of the original fermion theory.
