The agreement distance of rooted phylogenetic networks [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2019
The minimal number of rooted subtree prune and regraft (rSPR) operations needed to transform one phylogenetic tree into another one induces a metric on phylogenetic trees - the rSPR-distance.

On the existence of block-transitive combinatorial designs [PDF]

open access: yes, 2010
Block-transitive Steiner $t$-designs form a central part of the study of highly symmetric combinatorial configurations at the interface of several disciplines, including group theory, geometry, combinatorics, coding and information theory, and ...

Towards an Algebra for Cascade Effects [PDF]

open access: yesLogical Methods in Computer Science, 2017
We introduce a new class of (dynamical) systems that inherently capture cascading effects (viewed as consequential effects) and are naturally amenable to combinations.

Discrete Mathematics

open access: yes, 2022
In this volume, the authors present a self-contained introduction to discrete mathematics – the science of finite and countably infinite structures. In addition to taking a theoretical approach, they also include many practical exercises. The text covers

Counting descents, rises, and levels, with prescribed first element, in words [PDF]

open access: yes, 2006
Recently, Kitaev and Remmel [Classifying descents according to parity, Annals of Combinatorics, to appear 2007] refined the well-known permutation statistic ``descent'' by fixing parity of one of the descent's numbers. Results in that paper were extended

An Alternate Proof of Near-Optimal Light Spanners [PDF]

open access: yesTheoretiCS
In 2016, a breakthrough result of Chechik and Wulff-Nilsen [SODA '16] established that every $n$-node graph $G$ has a $(1+\varepsilon)(2k-1)$-spanner of lightness $O_{\varepsilon}(n^{1/k})$, and recent followup work by Le and Solomon [STOC '23 ...
