Hurwitz Stacks of Groups Extensions and Irreducibility
Benjamin Collas, Sylvain Maugeais
We study the irreducible components of special loci of curves whose group of symmetries is given as certain group extension. We introduce some relative Hurwitz data, which we show…
On Galois action on stack inertia of moduli spaces of curves
Benjamin Collas, Sylvain Maugeais
We establish that the geometric action of the absolute Galois group on the étale fundamental group of moduli spaces of curves induces a Galois action on its stack inertia subgroups…
On a compactification of a Hurwitz space in the wild case
Sylvain Maugeais
Let and be two integers and a prime number. Denote by the moduli space of morphisms of degree between smooth curves of genus and …
Théorie des déformations équivariantes des morphismes localement d'intersection complète
Sylvain Maugeais
This is an expository paper on the subject of the title. It assumes basic scheme theory, commutative and homological algebra.
