SUMMARY:On classes of planar maps with $lpha$-orientations having geometr
 ic interpretations - Schaeffer\, G (cole Polytechnique)

DESCRIPTION:Fixed out-degree orientations or $lpha$-orientations play a c
 entral rle in the so-called master bijections relating various families of
  planar maps to simple varieties of trees. I will discuss several known ca
 ses in which these orientations also provide purely combinatorial ways to 
 compute geometric representations. \n
