Abstract
We consider the concept of the Hausdorff analyticity for functions ranged in real algebras and the corresponding notion of the Hausdorff derivative. Both apply to the real algebra \(\mathbb {H}\) of Hamilton’s quaternions. The main aim of the work is to compare them with the well-known classes of \(\mathbb {H}\)-valued functions which have their own definitions of the derivative.
