Combinatorics on words in information security: Unavoidable regularities in the construction of multicollision attacks on iterated hash functions [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2011
Classically in combinatorics on words one studies unavoidable regularities that appear in sufficiently long strings of symbols over a fixed size alphabet.

String Attractors and Combinatorics on Words [PDF]

open access: yesCoRR, 2019
The notion of \emph{string attractor} has recently been introduced in [Prezza, 2017] and studied in [Kempa and Prezza, 2018] to provide a unifying framework for known dictionary-based compressors. A string attractor for a word $w=w[1]w[2]\cdots w[n]$ is a subset $Γ$ of the positions $\{1,\ldots,n\}$, such that all distinct factors of $w$ have an ...

The number of distinct adjacent pairs in geometrically distributed words: a probabilistic and combinatorial analysis [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2023
The analysis of strings of $n$ random variables with geometric distribution has recently attracted renewed interest: Archibald et al. consider the number of distinct adjacent pairs in geometrically distributed words.

What Dynamic Approaches Have Taught Us About Cognition and What They Have Not: On Values in Motion and the Importance of Replicable Forms

open access: yesTopics in Cognitive Science, EarlyView., 2023
Abstract Over the past several decades, research in the cognitive sciences has foregrounded the importance of active bodies and their continuous dependence on the changing environment, strengthening the relevance of dynamical models. These models have been steadily developed within the ecological psychology approach to cognition, which arguably ...

Sweep maps for lattice paths [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2014
Sweep maps are a family of maps on words that, while simple to define, are not yet known to be injective in general. This family subsumes many of the "zeta maps" that have arisen in the study of q,t-Catalan numbers in the course of relating the three ...

On morphisms preserving infinite Lyndon words [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2007
In a previous paper, we characterized free monoid morphisms preserving finite Lyndon words. In particular, we proved that such a morphism preserves the order on finite words.

Frequency-Hopping Sequences With Optimal Average Hamming Correlation and Their Applications in Energy and Spectrum Harvesting Technologies Area

open access: yesIEEE Access, 2021
The research of cyclotomy theory can be traced to Gauss and it has been applied to many fields such as cryptography, coding theory, and combinatorics. According to $v$ prime numbers or compound words, the incision on the residue-like ring ${\mathbb Z ...
