Keywords: | Quasi-definite linear functionals; Classical discrete polynomials; q-polynomials; Krall-type polynomials; Orthogonal polynomials; Addition of delta Dirac masses | Issue Date: | 2004 | Citation: | Journal of Mathematical Analysis and Applications. 295:1 (2004) 55-69 | Abstract: | In this paper we present a unified theory for studying the so-called Krall-type discrete orthogonal polynomials. In particular, the three-term recurrence relation, lowering and raising operators as well as the second order linear difference equation that the sequences of monic orthogonal polynomials satisfy are established. Some relevant examples of q-Krall polynomials are considered in detail. | URI: | https://hdl.handle.net/10316/4636 | DOI: | 10.1016/j.jmaa.2004.02.042 | Rights: | openAccess |
