  • A Computational Approach to Measuring Vote Elasticity and Competitiveness
    A Computational Approach to Measuring Vote Elasticity and Competitiveness Daryl DeFord∗ CSAIL, Massachusetts Institute of Technology Moon Duchin Department of Mathematics, Tufts University Justin Solomon CSAIL, Massachusetts Institute of Technology May 27, 2020 Abstract The recent wave of attention to partisan gerrymandering has come with a push to refine or replace the laws that govern political redistricting around the country. A common element in several states' reform efforts has been the inclusion of com- petitiveness metrics, or scores that evaluate a districting plan based on the extent to which district-level outcomes are in play or are likely to be closely contested. In this paper, we examine several classes of competitiveness metrics motivated by recent reform proposals and then evaluate their potential outcomes across large ensembles of districting plans at the Congressional and state Senate levels. This is part of a growing literature using MCMC techniques from applied statistics to situate plans and criteria in the context of valid redistricting alternatives. Our empirical analysis focuses on five states|Utah, Georgia, Wisconsin, Virginia, and Massachusetts|chosen to represent a range of partisan attributes. We highlight arXiv:2005.12731v1 [cs.CY] 26 May 2020 situation-specific difficulties in creating good competitiveness metrics and show that optimizing competitiveness can produce unintended consequences on other partisan metrics. These results demonstrate the importance of (1) avoiding writing detailed metric constraints into long-lasting constitutional reform and (2) carrying out careful mathematical modeling on real geo-electoral data in each redistricting cycle. Keywords: Redistricting, Gerrymandering, Markov Chains, Competitiveness ∗The authors gratefully acknowledge the generous support of the Prof.

  • COUNTING PROBLEMS in MODULI SPACE in This Series of Lectures, We
    COUNTING PROBLEMS IN MODULI SPACE ALEX ESKIN In this series of lectures, we describe some counting problems in mod- uli space and outline their connection to the dynamics of the SL(2, R) action on moduli space. Much of this is presented in analogy with the space of lattices SL(n, R)/SL(n, Z). 1. LECTURE 1: Counting problems and volumes of strata Recall that Ωn = SL(n, R)/SL(n, Z) is the space of covolume 1 lattices in Rn. This space is non-compact, since we can have arbitrarily short vectors in a lattice. We will refer to moduli spaces of translation surfaces as defined in the lectures by Howard Masur in this volume [Ma1, Definition 6] as strata. Note that the case of n = 2 in the space of lattices and the case of the stratum H1(∅) boil down to the same thing, since we are considering the space of unit area holomoprphic 1-forms on tori, which is given by SL(2, R)/SL(2, Z). Let B(R) be the ball of radius R centered at 0 in Rn. For a given lattice ∆ ∈ Ωn. we would like to find out how many lattice points, that is, how many points of ∆ are contained in B(R). It is immediately clear that for a fixed lattice ∆, as R →∞, (1) |∆ ∩ B(R)| ∼ Vol(B(R)) = Vol(B(1))Rn. (i.e. the number of lattice points is asymptotic to the volume). How- ever, this is not uniform in ∆. A uniform upper bound can be given as follows: Let Rn be endowed with a Euclidean structure.
