Hartogs Extension Theorem for Functions with Values in Complex Clifford Algebras

A regular extension phenomenon of functions defined on Euclidean space with values in a Clifford algebra was studied by Le Hung Son in the 90’s using methods of Clifford analysis, a function theory which, is centred around the notion of a monogenic function, i.e. a null solution of the firstorder, vector-valued Dirac operator in \({\mathbb{R}}^m\).

The isotonic Clifford analysis is a refinement of the latter, which arises for even dimension. As such it also may be regarded as an elegant generalization to complex Clifford algebra-valued functions of both holomorphic functions of several complex variables and two-sided biregular function theories.

The aim of this article is to present a Hartogs theorem on isotonic extendability of functions on a suitable domain of \({\mathbb{R}}^{2n}, n \geq 2\). As an application, the extension problem for holomorphic functions and so for the two-sided biregular ones is discussed.
