Abstract

We investigate the Sandpile Model and Chip Firing Game and an extension of these modelson cycle graphs. The extended model consists of allowing a negative number of chips ateach vertex. We give the characterization of reachable configurations and of fixed pointsof each model. At the end, we give explicit formula for the number of their fixedpoints.
