Algebrodynamics: Shear-Free Null Congruences and New Types of Electromagnetic Fields

Abstract

We briefly present our version of noncommutative analysis over matrix algebras, the algebra of biquaternions ($\mathbb{B}$) in particular. We demonstrate that any $\mathbb{B}$-differentiable function gives rise to a null shear-free congruence (NSFC) on the $\mathbb{B}$-vector space $\mathbb{C}\mathbf{M}$ and on its Minkowski subspace $\mathbf{M}$. Making use of the Kerr--Penrose correspondence between NSFC and twistor functions, we obtain the general solution to the equations of $\mathbb{B}$-differentiability and demonstrate that the source of an NSFC is, generically, a world sheet of a string in $\mathbb{C}\mathbf{M}$. Any singular point, caustic of an NSFC, is located on the complex null cone of a point on the generating string. Further we describe symmetries and associated gauge and spinor fields, with two electromagnetic types among them. A number of familiar and novel examples of NSFC and their singular loci are described. Finally, we describe a conservative algebraic dynamics of a set of identical particles on the ``Unique Worldline'' and discuss the connections of the theory with the Feynman--Wheeler concept of ``One-Electron Universe''
