摘要

We have obtained two types of two-dimensional similarity reductions for the (2 +1)-dimensional Klein-Gordon system using the standard classical Lie group approach with computer algebra. The well-known one-dimensional reductions, radial and travelling reductions are equivalent to the two special cases of our general two-dimensional reductions.
