Hidden $U_q(sl(2))\otimes U_q(sl(2))$ Quantum Group Symmetry in Two Dimensional Gravity

E. Cremmer, J. -L. Gervais, J. Schnittger

In a previous paper, we proposed a construction of $U_q(sl(2))$ quantum group symmetry generators for 2d gravity, where we took the chiral vertex operators of the theory to be the…
