Abstract

We prove Bergman’s theorem [10] on centralizers by using generic matrices and Kontsevich’s quantization method. For any field k of positive characteristics, set A = k‹x₁, . .. , x_s› be a free associative algebra, then any centralizer &(f) of nontrivial element f∈A∖k is a ring of polynomials on a single variable. We also prove that there is no commutative subalgebra with transcendent degree ≥2 of A.
