Abstract

The photometric history of the events related to Gamma–Ray Bursts can be studied from the very beginning, or even before, if they are repeated (at least two times after the first event) by effect of gravitational lensing. These possibilities are analyzed for different kinds of lensing galaxies in the frame of their simple models.

Key words: gravitational lensing, gamma-rays: bursts
