DESCRIPTION:Many models in plasma physics can be derived from 
 a non canonical hamiltonian formulation expressed 
 using a Poisson bracket and a conserved Hamiltonia
 n.For long time simulations\, conservation of inva
 riants coming from the hamiltonian formulation are
  essential. This can be achieved in particular by 
 looking for a discrete Poisson bracket and Hamilto
 nian and then using splitting of either the bracke
 t or the hamiltonian.As examples we will consider 
 the Vlasov-Maxwell equations as well as hybrid flu
 id-kinetic models.We shall also show how dissipati
 ve effects can be added using a symmetric positive
  non definite bracket and a dissipated entropy.
