| contents | We establish three-term recurrence relations for the ${}_1ϕ_1$ and ${}_0ϕ_1$ basic hypergeometric series involving multiplicative shifts of the parameters and the variable by integer powers of q. The coefficients of these recurrence relations are shown to be uniquely determined by the shift indices and are given explicitly in terms of rational functions. These recurrence relations arise as confluent limits of previously established recurrence relations for the ${}_2ϕ_1$ basic hypergeometric series.
As an application, we derive three-term recurrence relations for Jackson's second and third q-Bessel functions. These recurrence relations involve additive shifts in the order and multiplicative q-shifts in the variable, and their coefficients include the known q-Lommel polynomials as special cases. |
