摘要
引入了泛多项式,给出了泛多项式的一种偏序结构,证明了一截段上[0,p]的泛多项式构成一个格,而且当p是线性时是一个分配格.最后给出了非模格,非分配的模格,非线性的分配格的例子.
Induced a concept of universal polynomials in which given a partial order and proved that a subset forms a lattice (theorem 1) and the lattice is distributive when p is linear (theorem 2), finally given examples of nou modular, non distributive modular, non linear distributive lattices.
