SUMMARY: (...): Logarithmic differential forms and and vector fields : geom
 etric and  differential aspects.
DESCRIPTION:: In this talk I will first recall Kyoji Saito's theory of loga
 rithmic differential forms and vector fields\, paying a particular attenti
 on to  the freeness condition\, and explain related problem\, notably the 
 logarithmic comparison question. I will also develop the notion of logarit
 hmic residues along a divisor. I will review a number of results by David 
 Mond and/or Mathias Schulze and myself\, including a property of symmetry 
  of the b-function and a characterisation of divisors with normal crossing
 s in codimension one. This characterization answers a question of K. Saito
 . I will\, according to the time left\, briefly explain explain recent dev
 elopments by Delphine Pol\, which concern the set of valuations of residue
 s along reduced plane curves.http://perso.math.univ-angers.fr/spip.php?rub
