Extended geometry and kinematics induced by biquaternionic and twistor structures
Vladimir V. Kassandrov, Nina V. Markova
The algebra of biquaternions possess a manifestly Lorentz invariant form and induces an extended space-time geometry. We consider the links between this complex pre-geometry and re…

New symmetries, conserved quantities and gauge nature of a free Dirac field
Vladimir V. Kassandrov, Nina V. Markova
We present and amplify some of our previous statements on non-canonical interrelations between the solutions to free Dirac equation (DE) and Klein-Gordon equation (KGE). We demonst…
