内容	Zeta elements are (non-canonical) generators of the motivic Lie algebra of the category of mixed Tate motives over Z. One of the ultimate goals of the study of zeta elements is to give explicit formulas for a choice of them, which can be applied to multiple zeta values. In this talk we will first explain approaches to this problem using elements in the polar double shuffle Lie algebra constructed by F. Brown and J. Ecalle independently, and then present our result and future project on Brown's and Ecalle's elements. This is a joint work with N. Matthes (Kyushu University).
