摘　　要：刻划了特征不为2及3的域上所有从一个第二对称积空间到另一个的保形如λu · u(u是向量且λ是纯量) 的可分解元素的加法映射.The author describes those additive mappings from a second symmetric product space to another, over a ?eld of characteristic not 2 or 3, which preserve decomposable elements of the form λu · u where u is a vector and λ is a scalar.

关 键 词：加法映射 对称矩阵 秩
