Özet

A symmetry analysis of some special classes of Friedmann-Robertson-Walker (FRW) universe and nonlinear wave equations in this geometry are performed. Conserved forms for the wave equation are constructed by the application of Noether's theorem. We illustrate how the symmetry structure is used to reduce the wave equation leading to some exact solutions.
