Abstract

In this note, we obtain asymptotic expected number of real zeros for random polynomials of the form fn(z) = Sigma(n)(j=0) a(j)(n)c(j)(n)z(j) where a(j)(n) are independent and identically distributed real random variables with bounded (2 + delta)th absolute moment and the deterministic numbers c(j)(n) are normalizing constants for the monomials z(j) within a weighted L-2-space induced by aradial weight function satisfying suitable smoothness and growth conditions.
