Spatially self-similar locally rotationally symmetric perfect fluid models

• Einstein's field equations for spatially self-similar locally rotationally symmetric perfect fluid models are investigated. The field equations are rewritten as a first-order system of autonomous ordinary differential equations. Dimensionless variables are chosen in such a way that the number of equations in the coupled system of differential equations is reduced as far as possible. The system is subsequently analysed qualitatively for some of the models. The nature of the singularities occurring in the models is discussed
