چکیده
We give an explicit description of $$\overline{{\mathcal {M}}}_{1,2}$$ as a weighted blow-up projective stack. use this to compute the Brauer group {M}}}_{1,2;S}$$ over any base scheme S where 6 is invertible, and integral Chow rings $${\mathcal {M}}_{1,2}$$ .

Topology of Moduli Spaces of Tropical Curves with Marked Points
In this paper we study topology of moduli spaces of tropical curves of genus g with n marked points. We view the moduli spaces as being imbedded in a larger space, which we call the moduli space of metric graphs with n marked points. We describe the shrinking bridges strong deformation retraction, which leads to a substantial simplification of all these moduli spaces. In the rest of the paper, ...
متن کاملModuli Spaces of Tropical Curves of Higher Genus with Marked Points and Homotopy Colimits
The main characters of this paper are the moduli spaces TMg,n of rational tropical curves of genus g with n marked points, with g ≥ 2. We reduce the study of the homotopy type of these spaces to the analysis of compact spaces Xg,n, which in turn possess natural representations as a homotopy colimits of diagrams of topological spaces over combinatorially defined generalized simplicial complexes ...
متن کاملBlow up Points of Solution Curves for a Semilinear Problem
We study a semilinear elliptic equation with an asymptotic linear nonlinearity. Exact multiplicity of solutions are obtained under various conditions on the nonlinearity and the spectrum set. Our method combines a bifurcation approach and Leray–Schauder degree theory.
متن کاملThe Cohomology Ring of the Real Locus of the Moduli Space of Stable Curves of Genus 0 with Marked Points
Let M0,n be the Deligne-Mumford compactification of the moduli space of algebraic curves of genus 0 with n marked points, labeled by 1, ..., n. This is a smooth projective variety defined over Q ([DM]), equipped with a natural action of the symmetric group Sn (by permuting the labels); its points are stable, possibly singular, curves of genus 0 with n labeled points. The geometry of this variet...
متن کاملSolvable Points on Genus One Curves
A genus one curve defined over Q which has points over Qp for all primes p may not have a rational point. It is natural to study the classes of Q-extensions over which all such curves obtain a global point. In this article, we show that every such genus one curve with semistable Jacobian has a point defined over a solvable extension of Q.
