On Extensions of a Theorem of Baxter

J. S. Geronimo, A. Martinez-Finkelshtein

We combine the Riemann-Hilbert approach with the techniques of Banach algebras to obtain an extension of Baxter's Theorem for polynomials orthogonal on the unit circle. This is acc…

Galois Corings and a Jacobson-Bourbaki type Correspondence

J. Cuadra, J. Gomez-Torrecillas

The Jacobson-Bourbaki Theorem for division rings was formulated in terms of corings by Sweedler in 1975. Finiteness conditions hypotheses are not required in this new approach. In…

Shannon entropy of symmetric Pollaczek polynomials

A. Martinez-Finkelshtein, J. F. Sanchez-Lara

We discuss the asymptotic behavior (as $n \to \infty$ ) of the entropic integrals $E_{n} = - \int_{- 1}^{1} lo g (p_{n}^{2} (x)) p_{n}^{2} (x) w (x) d x,$ and $$ F_n = -\int_{-1}^1 \log…
