On the linearization problem involving Pochhammer symbols and their q-analogues
Álvarez Nodarse, Renato; Quintero, Niurka R.; Rouveaux, André (Elsevier, 1999-07-15)In this paper we present a simple recurrent algorithm for solving the linearization problem involving some families of q-polynomials in the exponential lattice x(s)=c1qs+c3. Some simple examples are worked out in detail.
