Generically log smooth families via generators and relations

Simon Felten

Let $f : X \to A_{t}^{1}$ be an affine flat morphism of finite type, and let $V = f^{- 1} (0)$ . Then, we obtain a morphism of log schemes $f\colon (X|V) \to (\mathbb{A}^1_t|…

The logarithmic Bogomolov-Tian-Todorov theorem

Simon Felten, Andrea Petracci

We prove that the log smooth deformations of a proper log smooth saturated log Calabi-Yau space are unobstructed.

Log Smooth Deformation Theory via Gerstenhaber Algebras

Simon Felten

We construct a $k [[Q]]$ -linear predifferential graded Lie algebra $L_{X / S}^{*}$ associated to a log smooth and saturated morphism $f : X \to S$ and prove that it controls the…
