Bianchi Type I Magnetized String Cosmological Model in General Relativity
Abstract
Bianchi Type I magnetized string cosmological model following the techniques used by Letelier and Stachel, is investigated. To get a determinate model, we assume a condition ∊ = λ (geometric string) where ∊ is the rest energy density, λ the string tension density and expansion (θ) is proportional to eigen value σ_{1} ^{1} of shear tensor (σ _{ j } ^{ i }), which leads to A = ℓ ( BC)^{ n } where A, B, C are metric potentials and ℓ and n are constants. The behaviour of the model in presence and absence of magnetic field is discussed. The physical and geometrical aspects of the model are also discussed.
