摘要：
We study the orbits of both massive test particles and light rays in the background of(1+2)-dimensional space-time. In particular, we have obtained exact analytical solutions to the geodesic equations in terms of the Weierstrass function for the Einstein-Maxwell-Dilaton space-time. The trajectories in the(x - y) plane are shown as well, and the comparison with the neutral BTZ space-time is made.
