A partial word is a word that may have some unknown places known as “holes” and can be replaced by the symbols from the underlying alphabet. A partial word u is said to be primitive if there does not exist a word v such that u is contained in a nontrivial integer power of v. We study the preservation of primitivity in partial words by the effect of some point mutation operations. In this paper, we investigate the effect of exchanging two adjacent symbols and of substituting a symbol by another…

On Del-Robust Primitive Partial Words with One Hole

- Mathematics, Computer ScienceLATA
- 2016

A special class of words is characterized, del-robust primitive partial words with one hole, that remains primitive on deletion of any symbol or the hole, and it is proved that the language of non-del-robUST primitive partial Words with one Hole is not context-free.

On Operations Preserving Primitivity of Partial Words with One Hole

This work investigates operations that preserve the primitivity of partial words with one hole, or words that have an undefined position, and finds that all primitive binary partial words of length up to 11 can be generated.

Algorithmic Combinatorics on Partial Words

This paper focuses on two areas of algorithmic combinatorics on partial words, namely, pattern avoidance and subword complexity, and discusses recent contributions as well as a number of open problems.

Some operations preserving primitivity of words

The operations are chosen in such a way that in the case of a two-letter alphabet, all primitive words of length @?11 can be obtained from single letters.

Primitive Morphisms

- Computer Science, MathematicsInf. Process. Lett.

A variant of Fine and Wilf's theorem for partial words is proved, and extensions of some general combinatorial properties of words are given.

On the robustness of primitive words

- Computer Science, MathematicsDiscret. Appl. Math.

A helpful result for proving inherent ambiguity

- Computer ScienceMathematical systems theory
- 2005

A slightly stronger result is presented which can be used to prove the inherent ambiguity of certain context-free languages and is based on Bar-Hillel, Perles and Shamir's theorem.
