Abstract: We apply a symbolic approach of the general quadratic decomposition of polynomial sequences—presented in a previous article referenced herein—to polynomial sequences fulfilling specific orthogonal conditions towards two given functionals $$u_{0},u_{1}$$ u 0 , u 1…

Abstract: Abstract An interval analysis of uncertain bi-modular problems is presented by addressing the efficiency of deterministic solution and reduction of computational cost on the non-linear FE iteration. Firstly, the singularity of 2-D conventional bi-modular constitutive…

Abstract: In this paper, we consider the asymptotic behavior of Xfn(n)≔∑i=1nfn(xi), where xi,i=1,…,n form orthogonal polynomial ensembles and fn is a real-valued, bounded measurable function. Under the condition that VarXfn(n)→∞, the Berry-Esseen (BE) bound and Cramer…

Abstract: We obtain factorial moment identities for the Charlier, Meixner and Krawtchouk orthogonal polynomial ensembles. Building on earlier results by Ledoux [Elect. J. Probab. 10, (2005)], we find hypergeometric representations for the factorial moments when the…
