On the vertex operator algebra associated with rank one lattice we derive a
general formula for products of vertex operators in terms of generalized
homogeneous symmetric functions. As an application we realize Jack symmetric
functions of rectangular shapes as well as marked rectangular shapes.
We construct all fundamental modules for the two parameter quantum affine
algebra of type $A$ using a combinatorial model of Young diagrams. In
particular we also give a fermionic realization of the two-parameter quantum
affine algebra.
We introduce two-parameter quantum toroidal algebras of simply laced types
and provide their group theoretic realization using finite subgroups of
$SL_2(\mathbb C)$ via McKay correspondence. In particular our construction
contains a realization of the vertex representation of the two-parameter
quantum affine algebras of $ADE$ types.
