comment Why is the equivariant Euler class a character ?
I can only see the first sentence as a rephrasing of my question. Is the map you're talking about the identification between $H^\ast_T(pt)$ and $ST^\ast$ ? If yes, why must it map a weight to the corresponding line bundle over a point ? If not, what is it ?

Well, yes, but how the to prove that this is linear ? And it is the Lie derivative with respect to the vector field generated by $X$ and the action of $G$.
