Monogenic Differential Operators

Results in Mathematics, 1992
It is well-known that a homogeneous polynomial of degree \(k\) admits a harmonic Fischer decomposition. But when dealing with Clifford algebra- valued functions, this decomposition can be refined, since every spherical harmonic can be written as the sum of a so-called inner and an outer spherical monogenic.

Associative Differential Operations

The Annals of Mathematics, 1950
Die Bezeichnungen \(D\)-Körper, D. P., und die Symbole \(y_i = y_{i0}\), \(y_{ir}\) usw. haben dieselbe Bedeutung. wie in der unmittelbar vorangehenden Besprechung Zbl 0037.18402. Gebildet werden formale \glqq Potenzreihen\grqq{} \(\mathfrak A(y) = A^{(1)}(y) + A^{(2)}(y) + \cdots\), bei denen jeweils \(A^{(i)}(y)\) ein D. P.
