Reduction of Symmetry in Quaternionic Analysis and Invariant Trilinear Forms
Igor Frenkel, Matvei Libine
In our previous papers we repeatedly emphasized the special role in Quaternionic Analysis of the conformal group SU(2,2) and other real forms of its complexification SL(4,C). In pa…

Quasi Regular Functions in Quaternionic Analysis
Igor Frenkel, Matvei Libine
We study a new class of functions that arise naturally in quaternionic analysis, we call them "quasi regular functions". Like the well-known quaternionic regular functions, these f…
