Cartan, pour des familles de courbes rationnelles minimales sur des varietes projectives unireglees. Un invariant important de ce probleme d'equivalence est la variete des tangentes rationnelles minimales. Nous etudions le cas ou les varietes de tangentes rationnelles minimales aux points generiques forment une famille isotriviale. La question principale dans ce cas est: pour quelle variete projective Z une famille de courbes rationnelles minimales, dont les varietes de tangentes rationnelles minimales sont Z-isotriviales, est-elle localement equivalente au modele plat? Nous montrons que c'est le cas lorsque Z verifie certaines conditions de geometrie projective qui sont satisfaites pour une hypersurface non singuliere de degre > 4.","PeriodicalId":50971,"journal":{"name":"Annales Scientifiques De L Ecole Normale Superieure","volume":"33 1","pages":"607-620"},"PeriodicalIF":1.9,"publicationDate":"2009-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80781899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Take two holomorphic (parametrized by some analytic set defined on a neighborhood of $0$ in $Bbb C^p$, for some $p>0$) or differentiable (parametrized by an open neighborhood of $0$ in $Bbb R^p$, for some $p>0$) deformation families of compact complex manifolds. Assume they are pointwise isomorphic, that is for each point $t$ of the parameter space, the fiber over $t$ of the first family is biholomorphic to the fiber over $t$ of the second family. Then, under which conditions are the two families locally isomorphic at 0? In this article, we give a sufficient condition in the case of holomorphic families. We show then that, surprisingly, this condition is not sufficient in the case of differentiable families. We also describe different types of counterexamples and give some elements of classification of the counterexamples. These results rely on a geometric study of the Kuranishi space of a compact complex manifold.","PeriodicalId":50971,"journal":{"name":"Annales Scientifiques De L Ecole Normale Superieure","volume":"24 1","pages":"495-525"},"PeriodicalIF":1.9,"publicationDate":"2009-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88334289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
