THEORY OF QUATERNIONIC ANALYTIC FUNCTIONS
Four-dimensional analog to the theory of complex analytic functions.
It was developed in the 1930s by the mathematician Fueter. It is based
on a generalization of the Cauchy-Riemann equations, since the
possible alternatives of power series expansions or quaternion
differentiability do not produce useful theories. A number of useful
integral theorems follow from the theory. Sudbery provides an
excellent review. Deavours covers some of the same material less
thoroughly. Brackx discusses a further generalization to arbitrary
Clifford algebras.
