Mollin, R. A. Uniform distribution of Hasse invariants. (English) Zbl 0603.12008 Int. J. Math. Math. Sci. 8, 127-134 (1985). Algebras of uniformly distributed Hasse invariants (which form a subgroup of the Brauer group, containing the Schur subgroup) are studied. Some properties of such algebras are given, mainly concerning primitive roots \(\epsilon\) of unity. For example, the following result is established: if \(K_ 1\) and \(K_ 2\) are extensions of a number field F such that \(K_ 1K_ 2\) is normal over F, D is a division algebra over \(K_ 1\) with uniformly distributed Hasse invariants which has index m, and is \((n,K_ 2)\)-adequate, and if m is relatively prime to the index of \(K_ 1K_ 2\) in \(N_ 1K_ 2\), where \(N_ 1\) is the normal closure of \(K_ 1\), then \(\epsilon_{m/g}\) is in \(K_ 2\), where g is the g.c.d. of m and of the index of \(K_ 1\) in \(N_ 1\).
