Geometric properties of the Jackson and Hahn-Exton q-Bessel functions are studied. For each of them, three different normalizations are applied in such a way that the resulting functions are analytic in the unit disk of ...

Motivated by the recent solution of Karlin's conjecture, properties of functions in the Laguerre-Polya class are investigated. The main result of this paper establishes new moment inequalities fur a class of entire functions ...

The celebrated Turân inequalities P 2 n(x)-P n-x(x)P n+1(x) ≥ 0, x ε[-1,1], n ≥ 1, where P n(x) denotes the Legendre polynomial of degree n, are extended to inequalities for sums of products of four classical orthogonal ...

Let p(x) be a polynomial of degree n with only real zeros x(1) <= x(2) <= ... <= x(n). Consider their midpoints z(k) = (x(k) + x(k+1))/2 and the zeros xi(1) <= xi(2) <= ... <= xi(n-1) of p'(z). Motivated by a question posed ...

We prove that the signs of the Maclaurin coefficients of a wide class of entire functions that belong to the Laguerre-Polya class possess a regular behaviour.

For any pair of algebraic polynomials A(x) = n k=0 n k akxk and B(x) = n k=0 n k bkxk, their Schur-Szego composition is defined by ˝ (A ∗ n B)(x) = n k=0 n k akbkxk. Motivated by some recent results which show that ...
