Derived jet and arc spaces

Roi Docampo, Lance Edward Miller, C. Eric Overton-Walker

We study jet schemes and arc spaces in the context of derived algebraic geometry. Explicitly, we consider the jet and arc functors in the category of schemes and study their animat…

Juggler's friezes

Roi Docampo, Greg Muller

This note generalizes -friezes to configurations of numbers in which one of the boundary rows has been replaced by a ragged edge (described by a juggling function).…

On arc fibers of morphisms of schemes

Christopher Chiu, Tommaso de Fernex, Roi Docampo

Given a morphism of schemes over a field, we prove several finiteness results about the fibers of the induced map on arc spaces $f_\infty \colon X_\infty \to Y_\…

Embedding codimension of the space of arcs

Christopher Chiu, Tommaso de Fernex, Roi Docampo

We introduce a notion of embedding codimension of an arbitrary local ring, establish some general properties, and study in detail the case of arc spaces of schemes of finite type o…

Nash blow-ups of jet schemes

Tommaso de Fernex, Roi Docampo

Given an arbitrary projective birational morphism of varieties, we provide a natural and explicit way of constructing relative compactifications of the maps induced on the main com…

Differentials on the arc space

Tommaso de Fernex, Roi Docampo

The paper provides a description of the sheaves of Kähler differentials of the arc space and jet schemes of an arbitrary scheme where these sheaves are computed directly from the s…
