The real spectrum compactification of character varieties
Marc Burger, Alessandra Iozzi, Anne Parreau +1
We study the real spectrum compactification of character varieties of finitely generated groups in semisimple Lie groups. This provides a compactification with good topological pro…

Non-Archimedean Hilbert geometry and degenerations of real Hilbert geometries
Xenia Flamm, Anne Parreau
We develop a theory of Hilbert geometry over general ordered valued fields, associating with an open convex subset of the projective space a quotient Hilbert metric space. Under na…
