Abstract:In this paper we obtain a formula for the average density of the distribution of complex zeros of an algebraic polynomial with random coefficients. The coefficients are assumed independent identical normally distributed random variables with mean mgr and variance sgr2. The value of the average density for the case of mgr=0 and sgr2=1 was obtained previously. Some limits of the distribution of the complex zeros are provided using the presented formula.
Keywords:Number of complex zeros  real roots  complex roots  random algebraic polynomials  Jacobian of transformation
