Complex analysis nowadays has higher-dimensional analoga: the algebra of
complex numbers is replaced then by the non-commutative algebra of real
quaternions or by Clifford algebras. During the last 30 years the
so-called quaternionic and Clifford or hypercomplex analysis
successfully developed to a powerful theory with many applications in
analysis, engineering and mathematical physics. This textbook introduces
both to classical and higher-dimensional results based on a uniform
notion of holomorphy. Historical remarks, lots of examples, figures and
exercises accompany each chapter.
