Abstract
A general framework for describing many-boson systems with four kinds of bo son operators is proposed. The basic idea comes from a general theory of th e su(n)- and the su(n + 1)-algebra, recently given by the present authors. A mixed-mode coherent state and a classical counterpart of the original qua ntal system are formulated.
