Abstract
We present gamma-ray burst afterglow light curves in X-ray, optical and rad io bands for various distributions of accelerated electrons behind the shoc k. The effects of lateral expansion of the jet and of winds in typical Wolf -Rayet star on the evolution are discussed. The light curves in the radiati ve case decline more rapidly than those in the adiabatic case. Under the co mbined effect of jet expansion and wind environment, the light curves have the greatest deviation from those of the standard model. All these results refer to the relativistic phase.
