Mean number of real zeros of a random hyperbolic polynomial
Consider the random hyperbolic polynomial, f(x)=1pa1coshx+⋯+np×ancoshnx, in which n and p are integers such that n≥2, p≥0, and the coefficients ak(k=1,2,…,n) are independent, standard normally distributed random variables. If νnp is the mean number of real zeros of f(x), then we prove that νnp=π−1...
