Crystal monoids \& crystal bases: rewriting systems and biautomatic structures for plactic monoids of types , , , , and
Alan J. Cain, Robert D. Gray, António Malheiro
The vertices of any (combinatorial) Kashiwara crystal graph carry a natural monoid structure given by identifying words labelling vertices that appear in the same position of isomo…
On regularity and the word problem for free idempotent generated semigroups
Igor Dolinka, Robert D. Gray, Nik Ruškuc
The category of all idempotent generated semigroups with a prescribed structure of their idempotents (called the biordered set) has an initial object called the f…
Reconstructing phylogenetic level-1 networks from nondense binet and trinet sets
Katharina Huber, Leo van Iersel, Vincent Moulton +2
Binets and trinets are phylogenetic networks with two and three leaves, respectively. Here we consider the problem of deciding if there exists a binary level-1 phylogenetic network…
Efficient estimation of high-dimensional multivariate normal copula models with discrete spatial responses
Aristidis K. Nikoloulopoulos
The distributional transform (DT) is amongst the computational methods used for estimation of high-dimensional multivariate normal copula models with discrete responses. Its advant…
Scattering of Line-Ring Vortices in a Superfluid
Alberto Villois, Hayder Salman, Davide Proment
We study the scattering of vortex rings by a superfluid line vortex using the Gross-Pitaevskii equation in a parameter regime where a hydrodynamic description based on a vortex fil…
On the Jacquet Conjecture on the Local Converse Problem for p-adic GL_n
Moshe Adrian, Baiying Liu, Shaun Stevens +1
Based on previous results of Jiang, Nien and the third author, we prove that any two minimax unitarizable supercuspidals of GL_N that have the same depth and central character admi…
Some Banach spaces added by a Cohen real
Mirna Džamonja
We study certain Banach spaces that are added in the extension by one Cohen real. Specifically, we show that adding just one Cohen real to any model adds a Banach space of density…
Multiwavelet troubled-cell indicator for discontinuity detection of discontinuous Galerkin schemes
Mathea J. Vuik, Jennifer K. Ryan
In this paper, we introduce a new global troubled-cell indicator for the discontinuous Galerkin (DG) method in one- and two-dimensions. This is done by taking advantage of the glob…
Isotypic faithful -representations of -simple fiat -categories
Volodymyr Mazorchuk, Vanessa Miemietz
We introduce the class of isotypic -representations for finitary -categories and the notion of inflation of -representations. Under some natural assumptions we show that i…
Braid groups and quiver mutation
Joseph Grant, Bethany Marsh
We describe presentations of braid groups of type ADE and show how these presentations are compatible with mutation of quivers, building on work of Barot and Marsh for Coxeter grou…
Automorphism groups of countable algebraically closed graphs and endomorphisms of the random graph
Igor Dolinka, Robert D. Gray, Jillian D. McPhee +2
We establish links between countable algebraically closed graphs and the endomorphisms of the countable universal graph . As a consequence we show that, for any countable graph…
Clades and clans: a comparison study of two evolutionary models
Sha Zhu, Cuong Than, Taoyang Wu
The Yule-Harding-Kingman (YHK) model and the proportional to distinguishable arrangements (PDA) model are two binary tree generating models that are widely used in evolutionary bio…
The rational field is not universally definable in pseudo-exponentiation
Jonathan Kirby
We show that the field of rational numbers is not definable by a universal formula in Zilber's pseudo-exponential field.
Infinite primitive and distance transitive directed graphs of finite out-valency
Daniela Amato, David M. Evans
We give certain properties which are satisfied by the descendant set of a vertex in an infinite, primitive, distance transitive digraph of finite out-valency and provide a strong s…
Transitive 2-representations of finitary 2-categories
Volodymyr Mazorchuk, Vanessa Miemietz
In this article, we define and study the class of simple transitive -representations of finitary -categories. We prove a weak version of the classical Jordan-Hölder Theorem w…
Helicity conservation by flow across scales in reconnecting vortex links and knots
Martin W. Scheeler, Dustin Kleckner, Davide Proment +2
The conjecture that helicity (or knottedness) is a fundamental conserved quantity has a rich history in fluid mechanics, but the nature of this conservation in the presence of diss…
Spectrum-driven Planetary Deglaciation Due to Increases in Stellar Luminosity
Aomawa L. Shields, Cecilia M. Bitz, Victoria S. Meadows +2
Distant planets in globally ice-covered, "snowball", states may depend on increases in their host stars' luminosity to become hospitable for surface life. Using a General Circulati…
Block decomposition of the category of l-modular smooth representations of GL(n,F) and its inner forms
Vincent Sécherre, Shaun Stevens
Let F be a non-Archimedean locally compact field of residue characteristic p, let D be a finite dimensional central division F-algebra and let R be an algebraically closed field of…
Local interdefinability of Weierstrass elliptic functions
Gareth Jones, Jonathan Kirby, Tamara Servi
We explain which Weierstrass elliptic functions are locally definable from other elliptic functions and exponentiation in the context of o-minimal structures. The proofs make use o…
A route to thermalization in the -Fermi-Pasta-Ulam system
Miguel Onorato, Lara Vozella, Davide Proment +1
We study the original -Fermi-Pasta-Ulam (FPU) system with and masses connected by a nonlinear quadratic spring. Our approach is based on resonant wave-wave intera…
Countable locally 2-arc-transitive bipartite graphs
Robert D. Gray, John K. Truss
We present an order-theoretic approach to the study of countably infinite locally 2-arc-transitive bipartite graphs. Our approach is motivated by techniques developed by Warren and…
A strong geometric hyperbolicity property for directed graphs and monoids
Robert Gray, Mark Kambites
We introduce and study a strong "thin triangle"' condition for directed graphs, which generalises the usual notion of hyperbolicity for a metric space. We prove that finitely gener…
