Growth of central polynomials of algebras with involution

Central polynomials of graded algebras: Capturing their exponential growth

“…Moreover, we compare the central G-exponent with the G-exponent by proving that either exp G,z (A) = exp G (A) or exp G,z (A) = 0. Similar results were recently achieved for ordinary algebras in [19] and [20] and for algebras with involution in [25].…”
