Shortened universal cycles for permutations [PDF]

, 2022
Kitaev, Potapov, and Vajnovszki [On shortening u-cycles and u-words for permutations, Discrete Appl. Math, 2019] described how to shorten universal words for permutations, to length $n!+n-1-i(n-1)$ for any $i \in [(n-2)!]$, by introducing incomparable ...

Impact of primary production and net ecosystem metabolism on carbon and nutrient cycling at the land-sea interface

Frontiers in Marine Science
Estuaries are typically net heterotrophic systems and a source of CO2 to the atmosphere, while continental shelves are net CO2 sinks. Yet, primary production and net ecosystem metabolism (NEM) are variable, and this has implications for nutrient and ...

On Edge Irregular Reflexive Labellings for the Generalized Friendship Graphs

Mathematics, 2017
We study an edge irregular reflexive k-labelling for the generalized friendship graphs, also known as flowers (a symmetric collection of cycles meeting at a common vertex), and determine the exact value of the reflexive edge strength for several ...
