A general extension theorem for cohomology classes on non reduced analytic subspaces CAO Jun Yan,DEMAILLY Jean-Pierre&MATSUMURA Shin-ichi Abstract The main purpose of this paper is to generalize the celebrated L^2 extension theorem of Ohsawa and Takegoshi in several directions:The holomorphic sections to extend are taken in a possibly singular hermitian line bundle,the subvariety from which the extension is performed may be non reduced,the ambient manifold
