Query: Noncommutative geometry of the dihedral group D 6   We study the noncommutative geometry of the dihedral group D 6 using the
tools of quantum group theory. We explicit the torsion free regular spin
connection and the corresponding 'Levi-Civita' connection. Next, we nd the
Riemann curvature and its Ricci tensor. The main result is the Dirac operator
of a representation of the group which we nd the eigenvalues and the
eigenmodes.
