Forms of almost homogeneous varieties over perfect fields
L Moser-Jauslin, R Terpereau - arXiv preprint arXiv:2008.05197, 2020 - arxiv.org
We study the $ k $-forms of almost homogeneous varieties when $ k $ is a perfect base field.
More precisely, in a first part, we obtain criteria for the existence of $ k $-forms in the …

Real loci in (log) Calabi–Yau manifolds via Kato–Nakayama spaces of toric degenerations
H Argüz - European Journal of Mathematics, 2021 - Springer
We study the real loci of toric degenerations of complex varieties with reducible central fibre.
We show that the topology of such degenerations can be explicitly described via the Kato …
