Abstract: In this article we describe the algebraic data which is equivalent to giving an associative, noncommutative algebra over an integral -scheme (where is an algebraically closed field of characteristic ), which is locally free of rank . The description allows us to conclude that, essentially, all such are locally upper triangular matrices, with degenerations of a restricted form allowed.
