Let g 1 (ω), g 2 (ω), . . . , gn(ω) be independent and normally distributed random variables with mean zero and variance one. We show that, for large values of n, the expected number of times the random hyperbolic polynomial (1) , but decreases steadily as O(L) increases in magnitude and ultimately becomes negligible when n −1 log L/ √ n → ∞. 2010 AMS Mathematics subject classification.
