Abstract
One-parameter families of quaternionic linear-fractional transformations are defined in terms of the exponential mapping from the Lie algebra of PSL2 H. The invariance of loxodromic curves allows us to characterize the fixed points corresponding to the family exp(tX) in terms of the generator X∈ sl2 H. Certain degenerate cases are described; it is shown that for nonplanar loxodromes the generator is unique.
