STRING COSMOLOGY WITH MAGNETIC FIELD IN CYLINDRICALLY SYMMETRIC SPACE-TIME-REVISITED

A new class of cylindrically symmetric inhomogeneous string cosmological models in presence of electromagnetic field is investigated. We have assumed that F-12 is the only non-vanishing component of F-ij. The Maxwell's equations show that F-12 is the function of x alone whereas the magnetic permeability is the function of x and t both. Also, the Einstein field equations have been solved with string source in which magnetic field are absent. The physical and geometric aspects of the model in presence and absence of magnetic field are also discussed.
