The Askey-Wilson algebra AW(n) arises not only from tensor products of U_q(su(1,1)), but also as the commutant of n commuting rotations in q-oscillator representations of o_{q^{1/2}}(2n), and the two descriptions are linked by Howe duality.

The dual pair $\big(U_q(\mathfrak{su}(1,1)),\mathfrak{o}_{q^{1/2}}(2n)\big)$, $q$-oscillators and Askey-Wilson algebras
The Askey-Wilson algebra AW(n) arises not only from tensor products of U_q(su(1,1)), but also as the commutant of n commuting rotations in q-oscillator representations of o_{q^{1/2}}(2n), and the two descriptions are linked by Howe duality.
