Algebrodynamics in complex space-time and the complex-quaternionic   origin of Minkowski geometry
  We present a scheme of biquaternionic algebrodymamics based on a nonlinear generalization of the Cauchy-Riemann holomorphy conditions considered therein as fundamental field equations. The automorphism group SO(3,C) of the biquaternion algebra acts as a proper Lorentz group on a real space whose coordinates are bilinear in the complex coordinates of biquaternionic vector space. A new invariant of Lorentz transformations then arises - the geometric phase. This invariant can be responsible for the quantum properties of particles associated in this approach with field singularities. Some new notions are introduced, related to ``hidden'' complex dynamics: ``observable'' space-time, the ensemble of identical correlated particles-singularities (``duplicons'') and others.
