Charged cylindrically symmetric collapse in f(R) gravity

摘要

This paper investigates the charged cylindrically symmetric gravitational collapse with perfect fluid in f(R) gravity. We formulate dynamical equations using the Misner-Sharp formalism and study the effects of charge, energy density and effective pressure on the cylindrical collapse. We also establish a relationship between the Weyl tensor, energy density and dark source terms. For constant Ricci scalar, it is concluded that the spacetime is conformally flat if and only if the energy density is homogeneous.
