Homological stability for spaces of embedded surfaces
(Mathematical Sciences PublisherGeometry and Topology, 2017-05-10)
© 2017, Mathematical Sciences Publishers. All rights reserved.We study the space of oriented genus-g subsurfaces of a fixed manifold M and, in particular, its homological properties. We construct a “scanning map” which ...
The 1-2 model
(American Mathematical SocietyIn the Tradition of Ahlfors–Bers, VII, 2017)
The current paper is a short review of rigorous results for the 1-2 model. The 1-2 model on the hexagonal lattice is a model of statistical mechanics in which each vertex is constrained to have degree either 1 or 2. It was ...
Potential automorphy and the Leopoldt conjecture
(Johns Hopkins University PressAmerican Journal of Mathematics, 2017-10-01)
We study in this paper Hida's p-adic Hecke algebra for GL_n over a CM field F. Hida has made a conjecture about the dimension of these Hecke algebras, which he calls the non-abelian Leopoldt conjecture, and shown that his ...
Risk and Uncertainty Communication
(Annual ReviewsAnnual Review of Statistics and its Application, 2017-03-07)
This review briefly examines the vast range of techniques used to communicate risk assessments arising from statistical analysis. After discussing essential psychological and sociological issues, I focus on individual ...
Connective constants and height functions for Cayley graphs
(American Mathematical SocietyTransactions of the American Mathematical Society, 2017-03-31)
The connective constant $μ$($G$) of an infinite transitive graph $G$ is the exponential growth rate of the number of self-avoiding walks from a given origin. In earlier work of Grimmett and Li, a locality theorem was proved ...
Infinite loop spaces and positive scalar curvature
(SpringerInventiones Mathematicae, 2017-09-01)
We study the homotopy type of the space of metrics of positive scalar curvature on high-dimensional compact spin manifolds. Hitchin used the fact that there are no harmonic spinors on a manifold with positive scalar curvature ...
Four-Dimensional Weakly Self-avoiding Walk with Contact Self-attraction
(SpringerJournal of Statistical Physics, 2017-04-01)
We consider the critical behaviour of the continuous-time weakly self-avoiding walk with contact self-attraction on $\mathbb{Z}$$^{4}$, for sufficiently small attraction. We prove that the susceptibility and correlation ...
Undecidability and the developability of permutoids and rigid pseudogroups
(Cambridge University PressForum of Mathematics, Sigma, 2017-03-20)
A $\textit{permutoid}$ is a set of partial permutations that contains the identity and is such that partial compositions, when defined, have at most one extension in the set. In 2004 Peter Cameron conjectured that there ...
Radically filtered quasi-hereditary algebras and rigidity of tilting modules
(Cambridge University PressMathematical Proceedings of the Cambridge Philosophical Society, 2017-09)
Let $\textit{A}$ be a quasi-hereditary algebra. We prove that in many cases, a tilting module is rigid (i.e. has identical radical and socle series) if it does not have certain subquotients whose composition factors extend ...
Teichmüller spaces and bounded symmetric domains do not mix isometrically
(SpringerGeometric and Functional Analysis, 2017-06-01)
This paper shows that, in dimensions two or more, there are no holomorphic isometries between Teichüller spaces and bounded symmetric domains in their intrinsic Kobayashi metric.
