Abstract

Let 𝑉𝑛={𝑝(π‘₯)βˆˆβ„š[π‘₯]|deg𝑝(π‘₯)≀𝑛} be the (𝑛+1)-dimensional vector space over β„š. We show that {𝐸0(π‘₯),𝐸1(π‘₯),…,𝐸𝑛(π‘₯)} is a good basis for the space 𝑉𝑛, for our purpose of arithmetical and combinatorial applications. Thus, if 𝑝(π‘₯)βˆˆβ„š[π‘₯] is of degree 𝑛, then βˆ‘π‘(π‘₯)=𝑛𝑙=0𝑏𝑙𝐸𝑙(π‘₯) for some uniquely determined π‘π‘™βˆˆβ„š. In this paper we develop method for computing 𝑏𝑙 from the information of 𝑝(π‘₯).
