On a Riemann-Hilbert boundary value problem for $(φ,ψ)$-harmonic functions in $\mathbb{R}^m$
The purpose of this paper is to solve a kind of Riemann-Hilbert boundary value problem for $(φ,ψ)$-harmonic functions, which are linked with the use of two orthogonal basis of the Euclidean space $\mathbb{R}^m$. We approach this problem using the language of Clifford analysis for obtaining the explicit expression of the solution of the problem in a Jordan domain $Ω\subset\mathbb{R}^m$ with fractal boundary. One of the remarkable feature in this study is that the boundary data involves higher order Lipschitz class of functions.
