Abstract
Identify ℂ3 with the set of reduced biquaternions of the form z = z 0+ z 1e1 + z 2 e 2, where z i ∈ ℂ. For Ω⊂ ℂ3, let ω: Ω → ℂ3 be a function ω = ω0+ ω1 e 1+ ω2 e 2. We consider the solutions of Our system is a modification of a system introduced by Li Yucheng and Qiao Yuying and a complexification of a system introduced by H. Leutwiler. These Mk-solutions are connected with k-hyperbolic harmonic functions h by
where h satisfies
The k-hyperbolic harmonic functions are also connected to polyharmonic ones, Δk h is harmonic.
We find basic properties for Mk-solutions and k-hyperbolic harmonic functions and examine their bases.
