Cylindrically symmetric non-aligned Einstein-Maxwell solutions with rotation and pseudorotation of the types O and N
Hector Vargas Rodriguez
A new solution to the Einstein-Maxwell field equations is presented describing a cylindrically symmetric homogeneous cosmology. The solution is conformally flat, it possesses seven…
