Gauge fields and particle-like formations associated with shear-free null congruences
Vladimir V. Kassandrov, Vladimir N. Trishin
We consider Maxwell fields associated with any shear-free null geodesic congruence on Minkowski or Riemannian background space-time. Bounded singular loci of these fields are treat…

Effective connections and fields associated with shear-free null congruences
V. V. Kassandrov, V. N. Trishin
A special subclass of shear-free null congruences (SFC) is studied, with tangent vector field being a repeated principal null direction of the Weyl tensor. We demonstrate that this…
