On Catalan's conjecture

open access: yesJournal of Number Theory, 1990
AbstractWe prove by the theory of algebraic numbers a result (Theorem 3) which, together with our earlier results (Theorems 1 and 2), yields a simple procedure for showing that Catalan's equation xp − yq = 1 has only trivial solution (x, y) in integers for a large set of prime pairs (p, q) (cf. particularly Theorems 6 and 8).

Assessing the societal influence of academic research with ChatGPT: Impact case study evaluations

open access: yesJournal of the Association for Information Science and Technology, EarlyView.
Abstract Academics and departments are sometimes judged by how their research has benefited society. For example, the UK's Research Excellence Framework (REF) assesses Impact Case Studies (ICSs), which are five‐page evidence‐based claims of societal impacts.

A Catalan triangle

open access: yesDiscrete Mathematics, 1976
AbstractWe develop an arithmetic triangle similar to Pascal's triangle. The entries are interpreted in terms of numbers of pairs of nonintersecting paths in the first quadrant. The main applications are results about the Catalan numbers and various random walk problems.

An integral representation, complete monotonicity, and inequalities of the Catalan numbers

open access: yes, 2018
In the paper, by virtue of the Cauchy integral formula in the theory of complex functions, the authors establish an integral representation for the generating function of the Catalan numbers in combinatorics.

Wastewater‐Based Epidemiology as a Complementary Tool for Antimicrobial Resistance Surveillance: Overcoming Barriers to Integration

open access: yesBioEssays, EarlyView.
This commentary explores the potential of wastewater‐based epidemiology (WBE) as a complementary approach for antimicrobial resistance (AMR) surveillance. WBE may provide early, community‐level insights into resistance trends, supporting timely interventions.

Catalan pairs and Fishburn triples [PDF]

open access: yesarXiv, 2015
Disanto, Ferrari, Pinzani and Rinaldi have introduced the concept of 'Catalan pair', which is a pair of partial orders (S,R) satisfying certain axioms. They have shown that Catalan pairs provide a natural description of objects belonging to several classes enumerated by Catalan numbers. In this paper, we first introduce another axiomatic structure (T,

Fuss-Catalan numbers and planar partitions [PDF]

open access: yesarXiv, 2023
We show how the Fuss-Catalan numbers $ \frac{1}{p n+1}\binom{pn+1}{n}$ enter different problems of counting simple and multiple planar partitions.
