摘要

A string cosmological model based on Bianchi VI0 is examined as an inhomogeneous Bianchi VI0 model in general relativity. As a result of assuming that the ratio of string tension density \(\lambda\) to string rest density \(\rho\) is one i.e., \(\lambda :\rho =\) 1, the deterministic solution to Einstein's field equations can be derived. The model obtained is one that is expanded, sheared, and spun in order to obtain a deterministic solution. The model's physical characteristics as well as its geometrical properties are also discussed.
