DESCRIPTION:Prof. Éric Séré - (Université de Paris-Dauphine - FR)\nAbs
 tract:\n\n“I will present a definition of the ground state for the Dirac
 -Fock energy inspired of Lieb’s relaxed variational principle for Hartre
 e-Fock. This definition seems simpler and more suitable for theoretical an
 d numerical investigations than previous ones. Based on this approach\, I 
 will present existence results for the ground state of molecules and cryst
 als. The existence proof for this ground state suggests an algorithm for i
 ts computation\, that generalizes the ODA algorithm of Cances-Lebris. The 
 existence result for crystals is joint work with Isabelle Catto\, Long Men
 g and Eric Paturel. The implementation and testing of the algorithm is wor
 k in progress (Guillaume Legendre\, Maxime Chupin).”\n
