Central Limit Theorem for the number of real roots of random orthogonal
polynomials
Central Limit Theorem for the number of real roots of random orthogonal
polynomials
In this note we study the number of real roots of a wide class of random orthogonal polynomials with gaussian coefficients. Using the method of Wiener Chaos we show that the fluctuation in the bulk is asymptotically gaussian, even when the local correlations are not necessarily the same.
