Abstract
In this article we describe the algebraic data which is equivalent
to giving an associative, noncommutative algebra Ox over an integral fc-scheme
Y (where k is an algebraically closed field of characteristic ^ 3), which is locally
free of rank 3. The description allows us to conclude that, essentially, all such
are locally upper triangular 2x2 matrices, with degenerations of a restricted
form allowed.
