 -firing and Zero-forcing number of graphs.\nAbstract: In this talk, we wil
 l describe a couple of discrete dynamical systems on graphs. Namely, the c
 hip-firing and the zero-forcing processes.Then, we will relate these games
  on the graph with an algebraic invariant, called the algebraic co-rank, d
 efined through the determinantal ideals of the graph.More precisely, as we
  explore some examples, we will see how that the algebraic co-rank works a
 s a bound for different concepts.Finally, we will see a brief description 
 of known results, as well as open problems.\n
