A note on constructing infinite binary words with polynomial subword complexity [PDF]

open access: yes, 2013
Most of the constructions of infinite words having polynomial subword complexity are quite complicated, e.g., sequences of Toeplitz, sequences defined by billiards in the cube, etc.

The subword complexity of finite and infinite binary words

open access: yes, 2004
Let Aq be a q-letter alphabet and w be a finite or right infinite word on this alphabet. A subword of w is a block of consecutive letters of w. The subword complexity function of w assigns to each positive integer, n, the number, fw (n), of distinct ...

ν-Tamari lattices via subword complexes

open access: yesElectronic Notes in Discrete Mathematics, 2017
Abstract We show that the ν-Tamari lattices of Preville-Ratelle and Viennot can obtained as the duals of certain subword complexes. This generalizes a known result for the classical Tamari lattice, provides a simple description of the lattice property using certain bracket vectors of ν-trees, and gives (conjectural) insight on the geometry of more ...

Subword complexes and 2-truncated cubes [PDF]

open access: yesRussian Mathematical Surveys, 2014
For a Coxeter element $c$ of a finite Coxeter group, we consider a family of subword complexes parameterized by reduced expressions of the longest element. This family generalizes $c-$cluster complexes. We describe vertices of these complexes in terms of roots of the corresponding root system.

State complexity of the subword closure operation with applications to DNA coding

open access: yes, 2008
We are interested in the state complexity of languages that are defined via the subword closure operation. The subword closure of a set S of fixed-length words is the set of all words w for which any subword of w of the fixed length is in S. This type of

Colorings of regular trees with linear subword complexity: first examples and properties [PDF]

open access: yes, 2013
학위논문 (석사)-- 서울대학교 대학원 : 수리과학부, 2013. 8. 임선희.정규트리의 채색의 부분단어 복잡도는 채색된 반지름 n인 부분트리의 채색의 수를 b(n)으로 정의한 것이다. 본 논문은 부분단어 복잡도를 이용하여 정규트리의 채색을 연구한 결과이다. 부분단어 복잡도가 선형함수인 채색을 중점적으로 다루었으며 특히 부분단어 복잡도가 2n+2인 것을 다루었다.

On the shape of subword complexity sequences of finite words

open access: yesCoRR, 2013
The subword complexity of a word $w$ over a finite alphabet $\mathcal{A}$ is a function that assigns for each positive integer $n$, the number of distinct subwords of length $n$ in $w$. The subword complexity of a word is a good measure of the randomness of the word and gives insight to what the word itself looks like.

Complexity in Plasma - A Grand View of Self- Organization

open access: yes, 1994
"The central theme of the Complexity is the inquest of the creation of ordered structure in nature. Extensive computer simulations on plasmas have revealed that self-organization is governed by the three key processes, i.e.

A note on the subword complexes in Coxeter groups

open access: yes, 2008
We prove that the Stanley--Reisner ideal of the Alexander dual of the subword complexes in Coxeter groups has linear quotients with respect to the lexicographical order of the minimal monomial generators. As a consequence, we obtain a shelling order on the facets of the subword complex.
