Christoffel formula for kernel polynomials on the unit circle
Cleonice F. Bracciali, Andrei Martínez-Finkelshtein, A. Sri Ranga +1
Given a nontrivial positive measure on the unit circle, the associated Christoffel-Darboux kernels are , $n \geq…
Orthogonal Polynomials Associated with Complementary Chain Sequences
Kiran Kumar Behera, A. Sriranga, A. Swaminathan
Using the minimal parameter sequence of a given chain sequence, we introduce the concept of complementary chain sequences, which we view as perturbations of chain sequences. Using…
Extreme zeros in a sequence of para-orthogonal polynomials and bounds for the support of the measure
A. Martinez-Finkelshtein, A. Sri Ranga, Daniel O. Veronese
Given a non-trivial Borel measure on the unit circle , the corresponding reproducing (or Christoffel-Darboux) kernels with one of the variables fixed at consti…
Radii of starlikeness of some special functions
Árpád Baricz, Dimitar K. Dimitrov, Halit Orhan +1
Geometric properties of the classical Lommel and Struve functions, both of the first kind, are studied. For each of them, there different normalizations are applied in such a way t…
Para-orthogonal polynomials on the unit circle satisfying three term recurrence formulas
Cleonice F. Bracciali, Alagacone Sri Ranga, Anbhu Swaminathan
When a nontrivial measure on the unit circle satisfies the symmetry then the associated OPUC, say , are all real. In this case, Delsarte a…
A Favard type theorem for orthogonal polynomials on the unit circle from a three term recurrence formula
Kenier Castillo, Marisa Costa, A. Sri Ranga +1
The objective of this manuscript is to study directly the Favard type theorem associated with the three term recurrence formula % \[ R_{n+1}(z) = \big[(1+ic_{n+1})z+(1-ic_{n+1})\bi…
