DESCRIPTION:Filtration by ramification groups of the Galois group of an<br
 >extension of local fields with possibly imperfect residue fields is defin
 ed<br>by Abbes and the speaker. The graded quotients are abelian groups an
 d<br>annihilated by the residue characteristic. We discuss the main ingred
 ients of<br>the proof and the construction of injections of the character 
 groups of the<br>graded quotients.<br>
