Query: Kinematic self-similar locally rotationally symmetric models   A brief summary of results on kinematic self-similarities in general
relativity is given. Attention is focussed on locally rotationally symmetric
models admitting kinematic self-similar vectors. Coordinate expressions for the
metric and the kinematic self-similar vector are provided.
  Einstein's field equations for perfect fluid models are investigated and all
the homothetic perfect fluid solutions admitting a maximal four-parameter group
of isometries are given.
