Abstract

We consider a random algebraic polynomial where it's the
coefficients form a sequence of centered Gaussian random variables.
Moreover, we assume that the increments are independent normally dis-
tributed variables with mean zero. The coefficients can be considered as
n consecutive observations of a Brownian motion. Assuming the sym-
metric property of coefficients, we investigate some new and considerable
results about the distribution of zeros. We also prove that the expected number of real zeros of self algebraic polynomial is asymptotically of order log n.
