Block Combinatorics [PDF]

open access: greenTransactions of the American Mathematical Society, 2004
In this paper we extend the block combinatorics partition theorems of Hindman and Milliken in the setting of the recursive system of the block Schreier families (B^xi) consisting of families defined for every countable ordinal xi. Results contain (a) a block partition Ramsey theorem for every countable ordinal xi (Hindman's theorem corresponding to xi ...

Portable Food‐Freshness Prediction Platform Based on Colorimetric Barcode Combinatorics and Deep Convolutional Neural Networks

open access: yesAdvanced Materials, 2020
Artificial scent screening systems (known as electronic noses, E‐noses) have been researched extensively. A portable, automatic, and accurate, real‐time E‐nose requires both robust cross‐reactive sensing and fingerprint pattern recognition.

Combinatorics and topology of Kawai-Lewellen-Tye relations [PDF]

open access: yesJournal of High Energy Physics, 2017
A bstractWe revisit the relations between open and closed string scattering amplitudes discovered by Kawai, Lewellen, and Tye (KLT). We show that they emerge from the un-derlying algebro-topological identities known as the twisted period relations.

Combinatorics

open access: yesBicycle or Unicycle?, 1981
We compare two generalisations of the notion of hook lengths for partitions. We apply this in the context of the modular representation theory of Arike–Koike algebras. We show that the Schur element of a simple module is divisible by the Schur element of

On BMRN*-colouring of planar digraphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2021
In a recent work, Bensmail, Blanc, Cohen, Havet and Rocha, motivated by applications for TDMA scheduling problems, have introduced the notion of BMRN*-colouring of digraphs, which is a type of arc-colouring with particular colouring constraints.

Enumeration of bilaterally symmetric 3-noncrossing partitions [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
Schützenberger's theorem for the ordinary RSK correspondence naturally extends to Chen et. al's correspondence for matchings and partitions. Thus the counting of bilaterally symmetric $k$-noncrossing partitions naturally arises as an analogue for ...

The Real-rootedness of Eulerian Polynomials via the Hermite–Biehler Theorem [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2015
Based on the Hermite–Biehler theorem, we simultaneously prove the real-rootedness of Eulerian polynomials of type $D$ and the real-rootedness of affine Eulerian polynomials of type $B$, which were first obtained by Savage and Visontai by using the ...

Graph Theory and Additive Combinatorics

open access: yes, 2023
Using the dichotomy of structure and pseudorandomness as a central theme, this accessible text provides a modern introduction to extremal graph theory and additive combinatorics.
