In particular, we describe the bosonizations of the latter algebra, its highest weight representations, vertex operators and screening operators. Finally, we use this bosonization method to compute the vacuum-to-vacuum expectation values and the form factors of any local operator.78 pages, LatexQuantum AlgebraCondensed MatterHigh Energy Physics - Theorytext
