On the Finite Groupoid G(n)
In this paper we study the existence of commuting regular elements, verifying the notion left (right) commuting regular elements and its properties in the groupoid G(n). Also we show that G(n) contains commuting regular subsemigroup and give a necessary and sufficient condition for the groupoid G(n) to be commuting regular.
متن کاملNouvelles perspectives en extraction d'information
Les techniques dites d'extraction d'information (EI) ont connu un essor considérable ces dix dernières années. L'EI consiste à extraire de documents des informations précises et à les structurer sous une forme prédéfinie. Il s'agit en général de remplir des formulaires donnant certaines caractéristiques concernant des entités ou des événements évoqués dans les textes ainsi que des relations ent...
متن کاملN Average of g(n)
Let d n pn the n th prime for n and let dk n jdk n dk n j for k n A well known conjecture usually ascribed to Gilbreath but actually due to Proth in the th century says that dk for all k This paper reports on a computation that veri ed this conjecture for k It also discusses the evidence and the heuristics about this conjecture It is very likely that similar conjectures are also valid for many ...
متن کاملLinear preservers of g-row and g-column majorization on M_{n,m}
Let A and B be n × m matrices. The matrix B is said to be g-row majorized (respectively g-column majorized) by A, if every row (respectively column) of B, is g-majorized by the corresponding row (respectively column) of A. In this paper all kinds of g-majorization are studied on Mn,m, and the possible structure of their linear preservers will be found. Also all linear operators T : Mn,m ---> Mn...
متن کاملOn Sequences G n Satisfying G n = ( d + 2 ) G n − 1 − G n − 2 Ricky X . F . Chen Center for Combinatorics LPMC
In this note, we study a class of sequences Gn satisfying Gn = (d+2)Gn−1 −Gn−2. Note that the Fibonacci numbers Gn = F2n, n > 1 and Gn = F2n+1, n > 0 occur when d = 1 with suitable initial conditions. We present a general interpretation for this class of sequences in terms of ordered trees which we count by nodes and outdegrees. Further more, several other related integer sequences are also stu...
