Semisimple types for p-adic classical groups
Michitaka Miyauchi, Shaun Stevens
We construct, for any symplectic, unitary or special orthogonal group over a locally compact nonarchimedean local field of odd residual characteristic, a type for each Bernstein co…
Forecasting the underlying potential governing the time series of a dynamical system
V. N. Livina, G. Lohmann, M. Mudelsee +1
We introduce a technique of time series analysis, potential forecasting, which is based on dynamical propagation of the probability density of time series. We employ polynomial coe…
Mixed convection above a rotating disk
Jorge Arrieta-Sanagustin, Mark G. Blyth
Mixed convection above a horizontal disk rotating in a semi-infinite fluid is examined when the disk is heated so that its temperature varies quadratically with distance away from…
Affine Cellularity of Khovanov-Lauda-Rouquier algebras in type A
Alexander S. Kleshchev, Joseph W. Loubert, Vanessa Miemietz
We prove that the Khovanov-Lauda-Rouquier algebras $R_\al$ of type are (graded) affine cellular in the sense of Koenig and Xi. In fact, we establish a stronger property,…
Directions In Optical Angular Momentum
Matt M. Coles, David L. Andrews
For paraxial and non-paraxial light, numerous measures of electromagnetic attribute are expressible in terms of photon annihilation and creation. Accordingly, energy, angular momen…
Buildings, Extensions, and Volume Growth Entropy
Jayadev S. Athreya, Anish Ghosh, Amritanshu Prasad
Let F be a non-Archimedean local field and let E be a finite extension of F. Let G be a split semisimple F group. We discuss how to compare volumes on the Bruhat-Tits buildings B_E…
Quasiminimal structures and excellence
Martin Bays, Bradd Hart, Tapani Hyttinen +2
We show that the excellence axiom in the definition of Zilber's quasiminimal excellent classes is redundant, in that it follows from the other axioms. This substantially simplifies…
Reconstructing fully-resolved trees from triplet cover distances
Katharina T. Huber, Mike Steel
It is a classical result that any finite tree with positively weighted edges, and without vertices of degree 2, is uniquely determined by the weighted path distance between each pa…
Conjugacy action, induced representations and the Steinberg square for simple groups of Lie type
Gerhard Heide, Jan Saxl, Pham Huu Tiep +1
Let be a finite simple group of Lie type, and let be the permutation representation of associated with the action of on itself by conjugation. We prove that every…
Multiplicative inverses in short intervals
Stephan Baier
We give an alternative proof of a recent result by T.D. Browning and A. Haynes (arXiv:1204.6374v1) on multiplicative inverses in sequences of intervals and improve this result unde…
Lassoing and corraling rooted phylogenetic trees
Katharina T. Huber, Andrei-Alin Popescu
The construction of a dendogram on a set of individuals is a key component of a genomewide association study. However even with modern sequencing technologies the distances on the…
Approximating Steady States in Equilibrium and Nonequilibrium Condensates
Hayder Salman
We obtain approximations for the time-independent Gross-Pitaevskii (GP) and complex GP equation in two and three spatial dimensions by generalizing the divergence-free WKB method.…
Recognizing Treelike k-Dissimilarities
Sven Herrmann, Katharina T. Huber, Vincent Moulton +1
A k-dissimilarity D on a finite set X, |X| >= k, is a map from the set of size k subsets of X to the real numbers. Such maps naturally arise from edge-weighted trees T with leaf-se…
A Generalization of Martin's Axiom
David Asperó, Miguel Angel Mota
We define the chain condition. The corresponding forcing axiom is a generalization of Martin's Axiom and implies certain uniform failures of club--guessing on …
Computing the blocks of a quasi-median graph
Sven Herrmann, Vincent Moulton
Quasi-median graphs are a tool commonly used by evolutionary biologists to visualise the evolution of molecular sequences. As with any graph, a quasi-median graph can contain cut v…
Searching for Realizations of Finite Metric Spaces in Tight Spans
Sven Herrmann, Vincent Moulton, Andreas Spillner
An important problem that commonly arises in areas such as internet traffic-flow analysis, phylogenetics and electrical circuit design, is to find a representation of any given met…
Metric Diophantine approximation on homogeneous varieties
Anish Ghosh, Alexander Gorodnik, Amos Nevo
We develop the metric theory of Diophantine approximation on homogeneous varieties of semisimple algebraic groups and prove results analogous to the classical Khinchin and Jarnik t…
Ideals and finiteness conditions for subsemigroups
R. Gray, V. Maltcev, J. D. Mitchell +1
In this paper we consider a number of finiteness conditions for semigroups related to their ideal structure, and ask whether such conditions are preserved by sub- or supersemigroup…
Chirality and angular momentum in optical radiation
Matt M. Coles, David L. Andrews
This paper develops, in precise quantum electrodynamic terms, photonic attributes of the "optical chirality density", one of several measures long known to be conserved quantities…
Sequential closure in the space of measures
Piotr Borodulin-Nadzieja, Omar Selim
We show that there is a compact topological space carrying a measure which is not a weak* limit of finitely supported measures but is in the sequential closure of the set of such m…
Forcing consequences of PFA together with the continuum large
David Asperó, Miguel Angel Mota
We develop a new method for building forcing iterations with symmetric systems of structures as side conditions. Using our method we prove that the forcing axiom for the class of a…
Novel Distances for Dollo Data
Michael Woodhams, Dorothy A. Steane, Rebecca C. Jones +3
We investigate distances on binary (presence/absence) data in the context of a Dollo process, where a trait can only arise once on a phylogenetic tree but may be lost many times. W…
Metric intersection problems in Cayley graphs and the Stirling recursion
Teeraphong Phongpattanacharoen, Johannes Siemons
In the symmetric group Sym(n) with n at least 5 let H be a conjugacy class of elements of order 2 and let Γbe the Cayley graph whose vertex set is the group G generated by H (so G…
Automorphisms with exotic orbit growth
Stephan Baier, Sawian Jaidee, Shaun Stevens +1
We exhibit continua on two different growth scales in the dynamical Mertens' theorem for ergodic automorphisms of one-dimensional solenoids.
