Space–times with geodesic, shear‐free, twist‐free, nonexpanding rays. II

Reduced gravitational field equations are obtained for space–times with geodesic, shear‐free, twist‐free, and nonexpanding rays. No restrictions are imposed on either the Weyl tensor or the Ricci tensor, and a further restriction made previously that the spin coefficient τ vanish is also dropped. Sp...

Description
Summary:Reduced gravitational field equations are obtained for space–times with geodesic, shear‐free, twist‐free, and nonexpanding rays. No restrictions are imposed on either the Weyl tensor or the Ricci tensor, and a further restriction made previously that the spin coefficient τ vanish is also dropped. Special cases of Einstein–Maxwell space–times are investigated further.
