摘要：
Finite versions of W-algebras are introduced by considering (symplectic) reductions of finite dimensional simple Lie algebras. It is shown that a nonlinear su(2) algebra previously introduced by Rocek [Phys. Lett. B 255 (1991 ) 5541 is nothing but a finite analogue of W3(2) and therefore a reduction of sl3. Its unitary and non-unitary, reducible and irreducible highest weight representations are constructed.
