Query: Quantum "az+b" group at roots of unity: unitary representations   All unitary representations of the quantum ``az+b'' group are found. It turns
out that this quantum group is self dual i.e. all unitary representations are
'numbered' by elements of the same group. Moreover, the formula for all unitary
representations involving the quantum exponential function is proven.
