A linearized polynomial is called scattered if for any , the condition implies that y and z are -linearly dependent. In this paper two generalizations of the notion of a scattered linearized polynomial are provided and investigated. Let t be a nontrivial positive divisor of n. By weakening the property defining a scattered linearized polynomial, -partially scattered and -partially scattered linearized polynomials are introduced in such a way that the scattered linearized polynomials are precisely those which are both - and -partially scattered. Also, connections between partially scattered polynomials, linear sets and rank metric codes are exhibited.

部分分散的线性化多项式和秩度量代码
线性化多项式 如果有任何,则称为分散 , 条件 意味着y和z是- 线性相关。在本文中,提供并研究了散射线性化多项式概念的两种推广。令t是n的非平凡正除数。通过弱化定义分散线性化多项式的属性,- 部分分散和 - 部分分散的线性化多项式的引入方式是,分散的线性化多项式恰好是那些既是 - 和 - 部分分散。此外,还展示了部分分散多项式、线性集和秩度量代码之间的联系。
