Neutral representations in dimension and fields of moduli

Giulio Bresciani, Tianzhi Yang

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

Neutral representations of finite diagonalizable group schemes and fields of moduli

Giulio Bresciani, Angelo Vistoli, Tianzhi Yang

We introduce the notion of a neutral representation of a finite group, or finite group scheme, ; a representation with the property that if a gerbe over a fiel…

The section conjecture for the toric fundamental group over -adic fields

Giulio Bresciani

Loosely speaking, the toric fundamental group is the Tannaka dual of a category of vector bundles which become direct sums of line bundles on a finite étale cover. In characteristi…

Fields of definition of dynamical systems on . Improvements on a result of Silverman

Giulio Bresciani

J. Silverman proved that a dynamical system on descends to the field of moduli if it is polynomial or it has even degree, but for non-polynomial ones of odd degree…

Uniform bounds for fields of definition in projective spaces

Giulio Bresciani

We give a positive answer to a question of J. Doyle and J. Silverman about fields of definition of dynamical systems on . We prove that, for fixed , there exists…

Real versus complex plane curves

Giulio Bresciani

We prove that a smooth, complex plane curve of odd degree can be defined by a polynomial with real coefficients if and only if is isomorphic to its complex conjugate. Count…
