Nous obtenons des métriques kählériennes Ricci plates sur les espaces symétriques complexes de rang à partir d’un modèle asymptotique explicite, dont la géométrie à l’infini s’interprète en termes de la compactification magnifique de l’espace symétrique. Dans le cas hermitien, on retrouve les métriques de Biquard-Gauduchon mais on produit aussi des métriques nouvelles.
We obtain Ricci flat Kähler metrics on complex symmetric spaces of rank two by using an explicit asymptotic model whose geometry at infinity is interpreted in the wonderful compactification of the symmetric space. We recover the metrics of Biquard-Gauduchon in the Hermitian case and obtain in addition several new metrics.
