## Section: Overall Objectives

### Members complementarity

The members of the ALIEN project work in different places: Paris, Lille,
Reims and Nancy; they share the algebraic tool
and the non-asymptotic estimation goal, which constitute the
natural kernel of the project. Each of them contributes to both
theoretical and applied sides of the global project. The following
table draws up a scheme of some of their specialities. Of course,
*algebraic tools, identification and estimation* are not
recalled here since any member of ALIEN is concerned with.
