(2020)
Scintillators belong to the oldest types of radiati on detectors. Nowadays, for spectrometric purposes the use of semiconductive detectors is more common, but scintillation detectors are still in use for various specific ...

In this paper, we introduce mixed coloured permutations, permutations with certain coloured cycles, and study the enumerative properties of these combinatorial objects. We derive the generating function, closed forms, ...
Cím: Generalized Ordered Set Partitions
Szerző: ; ;
Dátum: 2020
Feltöltve: 2023-02-16
(2020)
In this paper, we consider ordered set partitions obtained by imposing conditions on the size of the lists, and such that the first r elements are in distinct blocks, respectively. We introduce a generalization of the Lah ...
