  In this paper, we consider the order m k-automorphisms of SL(2,k). We first
characterize the forms that order m k-automorphisms of SL(2,k) take and then we
simple conditions on matrices A and B, involving eigenvalues and the field that
the entries of A and B lie in, that are equivalent to isomorphy between the
order m k-automorphisms Inn_A and Inn_B. We examine the number of isomorphy
classes and conclude with examples for selected fields.
