  • This paper deals with monic orthogonal polynomial sequences (MOPS in short) generated by a Geronimus canonical spectral transformation of a positive Borel measure μ, i.e., (x − c)− 1 dμ(x) + Nδ(x − c), for some free parameter \(N\in{\rm{I\!R}}_{+}\) and shift c. We analyze the behavior of the corresponding MOPS. In particular, we obtain such a behavior when the mass N tends to infinity as well as we characterize the precise values of N such the smallest (respectively, the largest) zero of these… CONTINUE READING
