A Filtration of (q,t)-Catalan numbers
Advances in Applied Mathematics, 2008 We define new generalizations of (q,t)-Catalan numbers applying nabla operator on k-Schur functions indexed by column partitions. In some special cases, we give a combinatorial interpretation of these numbers using configurations of Dyck paths. In some other special cases, we also interpret these new polynomial as Hilbert series of explicit sub-modules

Sustainable Development, EarlyView.ABSTRACT This study examines the interplay between climate change, violent conflict and forced migration in the Middle East and North Africa (MENA), focusing on asylum flows to the European Union (EU). By integrating high‐resolution climate, conflict and socioeconomic data spanning 2000 to 2023, we develop a comprehensive empirical framework to ...

Tableau Cycling and Catalan Numbers
, 2007 We develop two combinatorial proofs of the fact that certain Young tableaux are counted by the Catalan numbers. The setting is a larger class of tableaux where labels increase along rows without attention to whether labels increase down columns. We define a new operation called tableau cycling. It is used to duplicate the reflection argument attributed

How Brazilian Public Universities Are Operationalizing The SDGs: Strategic Plans Analysis
Sustainable Development, EarlyView.ABSTRACT Despite the importance of universities for Sustainable Development, only a handful of studies have evaluated the implementation levels of SDGs in HEIs in Latin America. To fill this void, this study examines the strategic plans of 70 Brazilian public universities, which account for 92.8% of Federal Universities.

Catalan, Motzkin, and Riordan numbers
Discrete Mathematics, 1999 The article presents a unified overview of the Catalan and Motzkin numbers together with a third sequence called Riordan (ring) numbers [see \textit{J. Riordan}, J. Comb. Theory, Ser. A 19, 214-222 (1975; Zbl 0308.05115)], having wide range of applications.

Operationalizing the Waste Hierarchy Though A Synthetic Performance Indicator: Evidence From Spain
Sustainable Development, EarlyView.ABSTRACT Ensuring compliance with the European Union (EU) waste hierarchy is essential for advancing circular economy objectives and meeting legally binding municipal solid waste (MSW) targets. This study develops and applies the Waste Hierarchy Achievement Synthetic Indicator (WHASI), an innovative synthetic index designed to assess territorial ...

Limiting the Number of Possible CFG Derivative Trees During Grammar Induction with Catalan Numbers
MathematicsGrammar induction runs into a serious problem due to the exponential growth of the number of possible derivation trees as sentence length increases, which makes unsupervised parsing both computationally demanding and highly indeterminate.
