A sufficient condition for the fiber of the tangent bundle of a scheme and its Zariski tangent space to be isomorphic
Colas Bardavid
In this note, we give a simple necessary condition for the Zariski relative tangent space and the Grothendieck relative tangent space to be isomorphic.
On the geometrization of a lemma of differential Galois theory
Colas Bardavid
In this paper, we give a geometrization and a generalization of a lemma of differential Galois theory. This geometrization, in addition of giving a nice insight on this result, off…
Vector fields and differential schemes
Colas Bardavid
We define vector fields, leaves and trajectories for schemes. With these tools, we are able to give a geometrical interpretation and to generalize several results of differential G…
Profinite completion and double-dual : isomorphisms and counter-examples
Colas Bardavid
We define, for any group , finite approximations ; with this tool, we give a new presentation of the profinite completion of an abtract group . We the…
