(R) be a real Clifford algebra and Gan open connected set in R<sup>n</sup> . By [1], the function with val-ues in A<sub>n</sub> (R) may be written aswhere B ={r<sub>1</sub>,r<sub>2</sub>,…,r<sub>h</sub>} {1,2,…,n}represent that from the sum for’lst and 2nd indi-sates respectively, and we have the following result.Theorem A Function f (x) with values in A. (R) is regular in G if and only ifLet G be the unit hyperball and L the unit hypersphere. Cutting G by the plane: x<sub>3</sub>= a<sub>3</sub>, …,x<sub>n</sub> = a<sub>n</sub>(n3) , we obtain a section domain G<sub>a</sub> in the x<sub>1</sub>x<sub>2</sub> plane. Let L<sub>a</sub> be the boundary of G<sub>a</sub>, and its center is writ-ten as 0<sub> </sub> = (0,0,α<sub>3</sub>,...,α<sub>n</sub>) . 展开更多
