Addendum to the article `Global pluripotential theory over a trivially valued field'

Abstract: This note is an addendum to the paper Global pluripotential theory over a trivially valued field' by the present authors, in which we prove two results. Let $X$ be an irreducible projective variety over an algebraically closed field field $k$, and assume that $k$ has characteristic zero, or that $X$ has dimension at most two. We first prove that when $X$ is smooth, the envelope property holds for any numerical class on $X$. Then we prove that for $X$ possibly singular and for an ample numerical class, the Monge--Amp\ere energy of a bounded function is equal to the energy of its usc regularized plurisubharmonic envelope.
