Flimsy Spaces

Robin Khanfir, Béranger Seguin

We study $n$ -flimsy spaces, which are the topological spaces that remain connected when removing fewer than $n$ points but become disconnected when removing exactly $n$ points. We…

On matrices commuting with their Frobenius

Fabian Gundlach, Béranger Seguin

The Frobenius of a matrix $M$ with coefficients in $F ˉ_{p}$ is the matrix $σ (M)$ obtained by raising each coefficient to the $p$ -th power. We consider the question of co…

Counting two-step nilpotent wildly ramified extensions of function fields

Fabian Gundlach, Béranger Seguin

We study the asymptotic distribution of wildly ramified extensions of function fields in characteristic $p > 2$ , focusing on (certain) $p$ -groups of nilpotency class at most $2$ . R…
