Abstract

The unique positive zero of Fm (z) := z2m zm +1 zm 1 1 leads to analogues of 22nk(k even) by using hypergeometric func-tions. The minimal polynomials of these analogues are related to Cheby-shev polynomials, and the minimal polynomial of an analogue of 22nk(k even > 2) can be computed by using an analogue of 22n2. In this pa-per we show that the analogue of 22n2is the only real zero of its minimalpolynomial, and has a dierent representation, by using a polynomial ofsmaller degree than Fm (z).
