The q -boson-fermion realizations of quantum suprealgebra U q (gl(2/1))
Abstract
We show that our construction of realizations for Lie algebras and quantum algebras can be generalized to quantum superalgebras, too. We study an example of quantum superalgebra
U
q
(gl(2/1))
and give the boson-fermion realization with respect to one pair od q-deformed boson operator and 2 pairs of fermions.
