✦ Synopsis

We extend to arbitrary finite radical extensions the results of Barrera-Mora and Velez (J. Algebra 162 (1993), 295 301) concerning simple radical extensions and we obtain in terms of crossed homomorphisms new characterizations of Kneser extensions and 2-Cogalois extensions introduced by Albu and Nicolae (J. Number Theory 52 (1995), 299 318).

Let K be a field and K(α) be an extension field of K. If [K(α) : K] = 3, char K = 3, and the minimal polynomial of α over Kang (2000, Am. Math. Monthly, 107, 254-256) In this paper, we prove a similar result when [K(α) : K] = 4, char K = 2, and the minimal polynomial of α over K is T 4 -uT 2 -vT -w

An extension of composite degree over a finite field may be implemented in one or more steps, involving the implementation of zero or more intermediate fields. A comparison of the expected efficiency of different field extensions is made, using a known probabilistic algorithm to form each extension.
