摘要
We study the Hamiltonian reduction of affine Lie superalgebra sl(2\1)(1). Based on a scalar Lax operator formalism, we derive the free field realization of the classical topological algebra which appears in the c less-than-or-equal-to 1 non-critical strings. In the quantum case, we analyze the BRST cohomology to get the quantum free field expression of the algebra.
