摘要
在常曲率黎曼流形上,Calabi 算子是一个二阶线性微分算子,为 Killing 算子的值域提供局部可积条件。我们将该算子推广,以在可能时为黎曼局部对称空间提供二阶线性局部可积条件。具体而言,我们证明了该广义算子在不可约情形下总是有效,并精确指出了那些使其失效的乘积情形。

备注
17 pages. A spelling mistake has been corrected. Our proof of Proposition 5 has been improved. A missing curvature term has been added to (31): it does not effect the subsequent argument. Several improvements have been made. We now avoid using the Ambrose-Singer holonomy theorem
