Conjugates of characteristic Sturmian words generated by morphisms [PDF]

open access: yes, 2004
This article is concerned with characteristic Sturmian words of slope α and 1-α (denoted by cα and c1-α resp.), where α∈(0,1) is an irrational number such that α=[0;1+d1,d2,..., dn] with dn≥d1≥1.

BPS operators in N = 4 $$ \mathcal{N}=4 $$ SO(N) super Yang-Mills theory: plethysms, dominoes and words

open access: yesJournal of High Energy Physics, 2018
Permutations and associated algebras allow the construction of half and quarter BPS operators in maximally supersymmetric Yang Mills theory with U(N), SO(N) and Sp(N) gauge groups.

Powers in a class of A-strict standard episturmian words [PDF]

open access: yes, 2007
This paper concerns a specific class of strict standard episturmian words whose directive words resemble those of characteristic Sturmian words. In particular, we explicitly determine all integer powers occurring in such infinite words, extending recent ...

Occurrences of palindromes in characteristic Sturmian words [PDF]

open access: yes, 2006
This paper is concerned with palindromes occurring in characteristic Sturmian words cα of slope α, where α∈(0,1) is an irrational. As cα is a uniformly recurrent infinite word, any (palindromic) factor of cα occurs infinitely many times in cα with ...

No Animals Were Harmed in the Making of this Veal

open access: yesVoices in Bioethics, 2016
I was raised on a conventional Jewish-American meat- and potato-based diet during my first two decades. In response to an emerging awareness of health risks related to my typical fare and exposure to alternative diets and, occasionally, the philosophies ...

On the local-indicability cohen–lyndon theorem

open access: yes, 2011
For a group H and a subset X of H, we let HX denote the set {hxh?1 | h ? H, x ? X}, and when X is a free-generating set of H, we say that the set HX is a Whitehead subset of H. For a group F and an element r of F, we say that r is Cohen–Lyndon aspherical

Lyndon Words and Short Superstrings [PDF]

open access: yesProceedings of the Twenty-Fourth Annual ACM-SIAM Symposium on Discrete Algorithms, 2013
In the Shortest-Superstring problem, we are given a set of strings S and want to find a string that contains all strings in S as substrings and has minimum length. This is a classical problem in approximation and the best known approximation factor is 2 1/2, given by Sweedyk in 1999.

Order and quasiperiodicity in episturmian words [PDF]

open access: yes, 2007
We prove a refinement of a recent characterization of infinite episturmian words via lexicographic orderings (Glen-Justin-Pirillo, 2007). This allows us to easily characterize the strict episturmian words that are "infinite Lyndon words", i.e., those ...
