La lluita continua: socio-political debate and the linguistic landscape of a Catalan city
Social Semiotics, 2022 Recently, the Spanish state has cracked down on efforts to hold a public referendum on independence in Catalonia. To understand the local dimension, this article explores the linguistic landscape (LL) of Girona, a city in northeast Catalonia.

Logarithmically complete monotonicity of a function related to the Catalan-Qi function
Acta Universitatis Sapientiae: Mathematica, 2016 In the paper, the authors find necessary and sufficient conditions such that a function related to the Catalan-Qi function, which is an alternative generalization of the Catalan numbers, is logarithmically complete monotonic.

Catalan pairs: A relational-theoretic approach to Catalan numbers
Advances in Applied Mathematics, 2010 AbstractWe define the notion of a Catalan pair (which is a pair of binary relations (S,R) satisfying certain axioms) with the aim of giving a common language to several combinatorial interpretations of Catalan numbers. We show, in particular, that the second component R uniquely determines the pair, and we give a characterization of R in terms of ...

On the $H$-triangle of generalised nonnesting partitions [PDF]
Discrete Mathematics & Theoretical Computer Science, 2014 With a crystallographic root system $\Phi$ , there are associated two Catalan objects, the set of nonnesting partitions $NN(\Phi)$, and the cluster complex $\Delta (\Phi)$. These possess a number of enumerative coincidences, many of which are captured in

The Problem of Separatism in Modern Spain: the Catalan Question
Проблемы постсоветского пространства, 2022 Catalan nationalism, rooted in the 19th century, transformed into separatism in the 1980s, threatening the existence of the Spanish state. The unstable political situation in the country caused by the crisis of the party system and serious economic ...

Limnology and Oceanography, Volume 67, Issue 12, Page 2621-2634, December 2022., 2022 Abstract Headwater streams are control points for carbon dioxide (CO2) emissions to the atmosphere, with relative contributions to CO2 emission fluxes from lateral groundwater inputs widely assumed to overwhelm those from in‐stream metabolic processes.

Integral Representations of the Catalan Numbers and Their Applications
Mathematics, 2017 In the paper, the authors survey integral representations of the Catalan numbers and the Catalan–Qi function, discuss equivalent relations between these integral representations, supply alternative and new proofs of several integral representations ...

Cores with distinct parts and bigraded Fibonacci numbers
, 2017 The notion of $(a,b)$-cores is closely related to rational $(a,b)$ Dyck paths due to Anderson's bijection, and thus the number of $(a,a+1)$-cores is given by the Catalan number $C_a$.

Parametric Catalan numbers and Catalan triangles
Linear Algebra and its Applications, 2013 Abstract Here presented a generalization of Catalan numbers and Catalan triangles associated with two parameters based on the sequence characterization of Bell-type Riordan arrays. Among the generalized Catalan numbers, a class of large generalized Catalan numbers and a class of small generalized Catalan numbers are defined, which can be considered ...

Moments of combinatorial and Catalan numbers
Journal of Number Theory, 2010 In this paper we obtain the moments {m}m0 defined by. where (mn) is the usual combinatorial number. We also provide the moments in the Catalan triangle whose (n,p) entry is defined by. and, in particular, new identities involving the well-known Catalan numbers. © 2010 Elsevier Inc.
