چکیده
Partant des prédictions de Bogomolny–Schmit pour les ondes planaires aléatoires, dans années récentes relations profondes sont apparues entre lignes niveau champs aléatoires Gaussiens réguliers et la percolation. En théorie percolation, un ingrédient clé l’analyse connectivité globale est famille bornes indépendantes en échelle sur probabilités croisement le régime critique, connues sous nom d’estimées Russo–Seymour–Welsh (RSW). De même façon, établir estimées du type RSW ensembles nodaux une étape majeure compréhension rigoureuse ces relations. L’ensemble Kostlan modèle important polynômes homogènes Gaussiens. nodal naturel hypersurface projective réelle typique, dont peut être vu comme version statistique 16ème problème Hilbert. Dans cet article, nous établissons dimension 2, montrant ainsi relation courbes algébriques Les uniformes degré polynôme, valables toutes échelles pertinentes ; ceci, particulier, résout question posée récemment par Beffara–Gayet. Plus généralement, nos arguments conduisent à large classe d’ensembles fonctions régulières sphère ou tore plat.

Asymptotic variance and CLT for the number of zeros of Kostlan Shub Smale random polynomials
Article history: Received 28 April 2015 Accepted after revision 17 September 2015 Available online 29 October 2015 Presented by the Editorial Board In this note, we find the asymptotic main term of the variance of the number of roots of Kostlan–Shub–Smale random polynomials and prove a central limit theorem for this number of roots as the degree goes to infinity. © 2015 Académie des sciences.

متن کاملEstimates for Norms of Random Polynomials
This paper contains some estimates for the integral-uniform norm and the uniform norm of a wide class of random polynomials. The family of integraluniform norms introduced in [6] is a natural generalization of the maximum norm taken over a net. We prove some properties of the integral-uniform norms. The given application of the established estimates demonstrates that the integral-uniform norms ...

Let $ a_0 (omega), a_1 (omega), a_2 (omega), dots, a_n (omega)$ be a sequence of independent random variables defined on a fixed probability space $(Omega, Pr, A)$. There are many known results for the expected number of real zeros of a polynomial $ a_0 (omega) psi_0(x)+ a_1 (omega)psi_1 (x)+, a_2 (omega)psi_2 (x)+...

In the present investigation, we use the Horadam Polynomials to establish upper bounds for the second and third coefficients of functions belongs to a new subclass of analytic and $lambda$-pseudo-starlike bi-univalent functions defined in the open unit disk $U$. Also, we discuss Fekete-Szeg$ddot{o}$ problem for functions belongs to this subclass.
