O. Foda et al., NOTES ON HIGHEST WEIGHT MODULES OF THE ELLIPTIC ALGEBRA A(Q,P)(S(L)OVER-CAP(2)), Progress of theoretical physics. Supplement, (118), 1995, pp. 1-34
We discuss a construction of highest weight modules for the recently d
efined elliptic algebra A(q,p)(($$$) over cap sl(2)) and make several
conjectures concerning them. The modules are generated by the action o
f the components of the operator L on the highest weight vectors. We i
ntroduce the vertex operators Phi and Psi through their commutation r
elations with the L-operators. We present ordering rules for the L- an
d Phi-operators and find an upper bound for the number of linearly ind
ependent vectors generated by them, which agrees with the known charac
ters of ($$$) over cap sl(2) -modules.
