SUMMARY:Noémie Combe (I2M\, Aix-Marseille Université): Intrinsic invarian
 ts of complex algebraic surfaces
DESCRIPTION:Noémie Combe: In the 60’s\, L2 theory for -operator has beco
 me important through the works of Hormander\, Versentini and Andreotti. Th
 is theory has been very well developed for complex manifolds. Somehow\, it
  remains a problem to define an appropriate L2 theory for the -operator on
  singular spaces. A redefinition of a Dolbeault type of complex for singul
 ar spaces leads to the definition of L2 cohomology\, which is a tool that 
 provides intrinsic geometric invariants of arbitrary complex varieties. In
  this work\, we will use these tools to discuss a classification of comple
 x algebraic varieties in terms of triangulation and geometric invariants s
 uch as Ricci tensors\, sectional curvature and Ricci curvature. \n\n\n\n
