“…In earlier studies [
1, 2], the term “inframonogenic function” was used for solutions of a two‐sided or “sandwich” second‐order differential equation of the form
In the papers cited as well as in more recent work [
3–7], the symbol
refers to the Dirac operator
, where

, while
are the units of the Clifford algebra under consideration. A rather different theory results when one uses for
what is sometimes called the generalized Cauchy–Riemann (or Fueter) operator
, as we propose to carry out here.…”
