| Abstract: | We show that there is a quantum Slq(2) group symmetry in Hofstadter problem on square lattice. The cyclic representation of the quantum group is discussed and its application for computing the degeneracy density of the model is shown. |
| Keywords: | Hofstadter problem quantum Slq(2) group cyclic representation |
