对于广义库默尔型的超凯勒四元簇X,我们构造了切丛T_X的无穷小形变,其Yoneda平方非零,这是首个具有阻碍形变的稳定超全纯丛的例子
英文摘要
For a hyper-Kähler fourfold $X$ of generalized Kummer type, we construct an infinitesimal deformation of the tangent bundle $T_X$ with non-zero Yoneda square. This is the first example of a stable hyperholomorphic bundle with obstructed deformations.
