Tame nodal stacky curves

Martin Bishop, William C. Newman

In this paper we analyze the properties of tame nodal stacky curves, in particular twisted curves and \textit{doubly-twisted} curves. Our main results are a complete classification…

Chow rings of moduli spaces of genus 0 curves with collisions

William C. Newman

Introduced in [BB], simplicially stable spaces are alternative compactifications of $M_{g, n}$ generalizing Hassett's moduli spaces of weighted stable curves. We give pres…

The first higher Chow groups of $M_{1, n}$ for $n \leq 4$

William C. Newman

For $n \leq 4$ , we compute the indecomposible higher Chow groups $CH (M_{1, n}, 1)$ with integer coefficients. As an application, we give new proofs…
