Conjugacy on partial words [PDF]

open access: yesTheoretical Computer Science, 2002
The study of the combinatorial properties of strings of symbols from a finite alphabet (also referred to as words) is profoundly connected to numerous fields such as biology, computer science, mathematics, and physics.

Unavoidable Sets of Partial Words [PDF]

open access: yesTheory of Computing Systems, 2009
The notion of an unavoidable set of words appears frequently in the fields of mathematics and theoretical computer science, in particular with its connection to the study of combinatorics on words.

Unbordered partial words [PDF]

open access: yesDiscrete Applied Mathematics, 2008
An unbordered word is a string over a finite alphabet such that none of its proper prefixes is one of its suffixes. In this paper, we extend the results on unbordered words to unbordered partial words. Partial words are strings that may have a number of “

Equations on partial words [PDF]

open access: yesRAIRO - Theoretical Informatics and Applications, 2006
Summary: It is well-known that some of the most basic properties of words, like the commutativity \((xy = yx)\) and the conjugacy \((xz = zy)\), can be expressed as solutions of word equations. An important problem is to decide whether or not a given equation on words has a solution.

Pattern avoidance in partial permutations [PDF]

open access: yes, 2011
Motivated by the concept of partial words, we introduce an analogous concept of partial permutations. A partial permutation of length n with k holes is a sequence of symbols $\pi = \pi_1\pi_2 ...

On the number of squares in partial words [PDF]

open access: yesRAIRO - Theoretical Informatics and Applications, 2010
Summary: The theorem of Fraenkel and Simpson states that the maximum number of distinct squares that a word \(w\) of length \(n\) can contain is less than \(2n\). This is based on the fact that no more than two squares can have their last occurrences starting at the same position.
