Question about action of exponential of Lie algebras (Faraut and Koranyi's book)
@LSpice Thank you for your comment. I don't understand why $X \cdot e = Y \cdot e$ would imply that $X^n \cdot e = Y^n \cdot e$?

When does an inner product on $C(K)$ come from integration?
@Gerald Edgar Yes, I suppose you can integrate nonzero functions to zero.

Consider a net of weak order units in a Riesz space converging in order to a weak order unit. Is there a tail whose infimum is a weak order unit?

@erz Yes, of course. This is Corollary I.1.4 in "Compact convex sets and boundary integrals" by E. M. Alfsen.
