Abstract

Let f=(f1,,fn)f=(f_1,\ldots,f_n) be a system of nn complex homogeneous polynomials in nn variables of degree dd. We call λC\lambda\in\mathbb{C} an eigenvalue of ff if there exists vCn\{0}v\in\mathbb{C}^n\backslash\{0\} with f(v)=λvf(v)=\lambda v, generalizing the case of eigenvalues of matrices (d=1d=1). We derive the distribution of λ\lambda when the fif_i are independently chosen at random according to the unitary invariant Weyl distribution and determine the limit distribution for nn\to\infty.
