Jumbled Simon's Equivalence and Embeddings

Pamela Fleischmann, Annika Huch, Sungmin Kim +2

\emph{Jumbled scattered factors} are a generalisation of scattered factors (or subsequences) where a jumbled scattered factor is obtained from another word by deleting and rearrang…

Witness Languages for Pumping Lemmata

Pamela Fleischmann, Annika Huch, Christian Rauch

In 2022 Dassow and Jecker started investigations on the operational complexity of the pumping constant w.r.t.~two pumping lemmata. Since then, the research on pumping lemmata emerg…

-word--representable Graphs

Duncan Adamson, Amanita Dietz, Pamela Fleischmann +2

This paper investigates the new notion of -word--repre\-sentable graphs: the nodes of the graph correspond to the letters of the two words and there exists an edge between tw…

(Sets of ) Complement Scattered Factors

Duncan Adamson, Pamela Fleischmann, Annika Huch

Starting in the 1970s with the fundamental work of Imre Simon, \emph{scattered factors} (also known as subsequences or scattered subwords) have remained a consistently and heavily…

Word Chain Generators for Prefix Normal Words

Duncan Adamson, Moritz Dudey, Pamela Fleischmann +1

In 2011, Fici and Lipták introduced prefix normal words. A binary word is prefix normal if it has no factor (substring) that contains more occurrences of the letter 1 than the pref…

Word-Representable Graphs and Locality of Words

Philipp Böll, Pamela Fleischmann, Annika Huch +4

In this work, we investigate the relationship between -repre\-sentable graphs and graphs representable by -local words. In particular, we show that every graph representable…

Jumbled Scattered Factors

Pamela Fleischmann, Annika Huch, Melf Kammholz +1

In this work, we combine the research on (absent) scattered factors with the one of jumbled words. For instance, is an absent scattered factor of $\mathtt{cauliflow…

-Universality of Regular Languages Revisited

Duncan Adamson, Pamela Fleischmann, Annika Huch +2

A subsequence of a word is a word such that , for some set of indices . A word is \e…

-local Graphs

Christian Beth, Pamela Fleischmann, Annika Huch +4

In 2017 Day et al. introduced the notion of locality as a structural complexity-measure for patterns in the field of pattern matching established by Angluin in 1980. In 2019 Casel…

Rollercoasters with Plateaus

Duncan Adamson, Pamela Fleischmann, Annika Huch

In this paper we investigate the problem of detecting, counting, and enumerating (generating) all maximum length plateau--rollercoasters appearing as a subsequence of some given…

Tight Bounds for the Number of Absent Subsequences

Duncan Adamson, Pamela Fleischmann, Annika Huch +3

A {\em subsequence} of a word is a word that can be obtained by deleting some letters from while maintaining the relative order of the remaining letters, e.g., $\mathtt…

-Universality of Regular Languages

Duncan Adamson, Pamela Fleischmann, Annika Huch +3

A subsequence of a word is a word such that , for some set of indices . A word is…

--Factorization and the Binary Case of Simon's Congruence

Pamela Fleischmann, Jonas Höfer, Annika Huch +1

In 1991 Hébrard introduced a factorization of words that turned out to be a powerful tool for the investigation of a word's scattered factors (also known as (scattered) subwords or…

m-Nearly k-Universal Words -- Investigating Simon Congruence

Pamela Fleischmann, Lukas Haschke, Annika Huch +2

Determining the index of the Simon congruence is a long outstanding open problem. Two words and are called Simon congruent if they have the same set of scattered factors, w…
