q-Eulerian Polynomials and Polynomials with Only Real Zeros
نویسندگان
چکیده
Let f and F be two polynomials satisfying F (x) = u(x)f(x) + v(x)f (x). We characterize the relation between the location and multiplicity of the real zeros of f and F , which generalizes and unifies many known results, including the results of Brenti and Brändén about the q-Eulerian polynomials.

Ju l 2 00 6 A unified approach to polynomial sequences with only real zeros ∗
We give new sufficient conditions for a sequence of polynomials to have only real zeros based on the method of interlacing zeros. As applications we derive several well-known facts, including the reality of zeros of orthogonal polynomials, matching polynomials, Narayana polynomials and Eulerian polynomials. We also settle certain conjectures of Stahl on genus polynomials by proving them for cer...

متن کاملOn the Real-Rootedness of the Descent Polynomials of (n-2)-Stack Sortable Permutations
Bóna conjectured that the descent polynomials on (n−2)-stack sortable permutations have only real zeros. Brändén proved this conjecture by establishing a more general result. In this paper, we give another proof of Brändén’s result by using the theory of s-Eulerian polynomials recently developed by Savage and Visontai.
متن کاملDomain of attraction of normal law and zeros of random polynomials
Let$ P_{n}(x)= sum_{i=0}^{n} A_{i}x^{i}$ be a random algebraicpolynomial, where $A_{0},A_{1}, cdots $ is a sequence of independent random variables belong to the domain of attraction of the normal law. Thus $A_j$'s for $j=0,1cdots $ possesses the characteristic functions $exp {-frac{1}{2}t^{2}H_{j}(t)}$, where $H_j(t)$'s are complex slowlyvarying functions.Under the assumption that there exist ...
