 We will describe in this talk how to define, given a three 
  
 dimensional closed contact manifold, a contact homology and we will 
  
 indicate how to indentify some of its generators. We will also establish 
  
 strong compactness properties on the flow-lines of the variational problem 
  
 that this homology involves.
