On the Fields of Moduli of Curves of Genus Six

Tianzhi Yang

The field of moduli of a variety $X$ over an algebraically closed field $K$ is defined as the fixed field of those automorphisms $I ¨ $ of $K$ for which $X ≅ X^{I ¨} $ . A fundamental…

Neutral representations in dimension $\leq 3$ and fields of moduli

Giulio Bresciani, Tianzhi Yang

A representation $V$ of an algebraic group $G$ induces a vector bundle $[V / G] \to B G$ . The representation $V$ of $G$ is neutral if, for every twisted form $\mathcal{V} \to \mathcal…
