Inverse scattering and Clifford analysis
We apply a Borel-Pompeiu formula for functions in ℂ n to investigate the existence of admissible data for the inverse scattering problem in three...

Hypermonogenic functions and Möbius transformations
Let Cl n be the (universal) Clifford algebra generated by e 1 , …, e n satisfying e i e j + e j e i =−2σ ij , i, j =1, …, n . The Dirac operator in Cl ...

On the Riemann Hilbert type problems in Clifford analysis
In this paper boundary value problems combining Jump — Riemann and Hilbert problems for monogenic functions in Ahlfors-David regular surfaces and in...

Rudolf Fueter and his motivation for hypercomplex function theory
Fifty years ago, on the 6th of August of 1950, Rudolf Fueter died in Brunnen, Switzerland, at the age of seventy. He wrote a remarkable chapter in...

New mean-value formulas for harmonic functions in polyhedral domains
We prove new mean value formulas for harmonic functions in polyhedra. Our approach is elementary and utilizes vanishing formulas for holomorphic...

Special monogenic polynomials andL 2-approximation
The paper features some observations about the behaviour of special monogenic polynomials in the unit ball of ℝ n which are relevant to the...

On finite difference Dirac operators and their fundamental solutions
Several finite difference approximations of the Dirac operator are studied and compared. Main goals are finite difference Dirac operators which allow...

On the conjugate of the Dirac operator
We analyse the behaviour of the Euclidean Dirac operator under a special transformation preserving monogenicity. The framework of Vahlen matrices (see

Index and wrap** number for paravectorvalued symbols
From classical complex analysis it is well-known that the index of the Riemann-Hilbert problem is connected with the winding number. How to...

Hyperholomorphic functions in ℝ3
We study a generalization of the Cauchy-Riemann system in ℝ 3 , which is based on the hyperbolic metric, and has the property that classical...

Applications of the monogenic functional calculus for noncommuting systems of operators
The connection between Clifford analysis and the Weyl functional calculus for a d -tuple of bounded selfadjoint operators is used to prove a geometric...

Models for irreducible representations ofSpin(m)
In this paper we consider harmonic and monogenic polynomials of simplicial type. It is proved that these polynomials provide explicit realizations of...

Singular integrals and Fourier multipliers on unit spheres and their Lipschitz perturbations
A theory of singular integrals with monogenic kernels on star-shaped Lipschitz surfaces in R n is established. The class of singular integrals forms...

e to the A, in a New Way, Some More to Say
Expressions are given for the exponential of a Hermitian matrix, A . Replacing A by iA these are explicit formulas for the Fourier transform of e ...

Boundary value problems for quaternionic monogenic functions on non-smooth sureaces
In this paper, analogous of the Compound Riemann-Hilbert boundary value problems are investigate for quaternionic monogenic functions. The solution...
