Real Zeros of a Class of Hyperbolic Polynomials with Random Coefficients

We have proved here that the expected number of real zeros of a random hyperbolic polynomial of the form y=Pnt=n1a1cosh⁡t+n2a2cosh⁡2t+⋯+nnancosh⁡nt, where a1,…,an is a sequence of standard Gaussian random variables, is n/2+op(1). It is shown that the asymptotic value of expected number of times the...
