INTEGRAL REPRESENTATIONS OF CATALAN NUMBERS AND THEIR APPLICATIONS
, 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 ...

Advanced Science, EarlyView.In this study, Merkoçi and his research group present a polymer‐based synthesis to enhance the stability of Prussian blue (PB) nanoparticles. The resulting PB‐infused catalytic hetero‐interface architecture (PB‐CHIA) achieves complete two‐dimensional (2D) and three‐dimensional (3D) substrate coverage (glassy carbon and laser‐induced graphene electrodes)

Catalan structures and Catalan pairs [PDF]
arXiv, 2010 A Catalan pair is a pair of binary relations (S,R) satisfying certain axioms. These objects are enumerated by the well-known Catalan numbers, and have been introduced with the aim of giving a common language to most of the structures counted by Catalan numbers.

Discrete 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.

Probus, 2012 Abstract In this paper, we will present an overview of compounding in Catalan, covering the founding theoretical-descriptive studies of the 20th century to the most recent scholarship. Specifically, it analyses the boundaries of compounding, considering the limits which make it possible to distinguish compounding from derivation and free syntagmas.

Advanced Energy Materials, EarlyView.Formamidinium‐based perovskite (FAPbI3) solar cells are of great interest due to an advantageous band gap able to achieve the maximum theoretical efficiency. In this study, a strategy is demonstrated based on a halide ion gradient (present in the general 2D perovskite formulation) created on the 3D FAPbI3 surface to simultaneously increase the ...

Catalan Tree & Parity of some sequences which are related to Catalan numbers [PDF]
arXiv, 2011 In this paper we determine the parity of some sequences which are related to Catalan numbers. Also we introduce a combinatorical object called, \Catalan tree", and discuss its properties.

Catalan triangles and tied arc diagrams [PDF]
arXiv, 2020 The Catalan triangle, as well as a Fuss-Catalan triangle, enter a problem of counting particular tied arc diagrams. This setting allows us to prove some combinatorial properties of these triangles.
