2 For a graph G on vertex set V with [absolute value of V|] = n, we will denote by Bij(V, [n]) the set of bijections
from V to [n].
We recall here the above-mentioned bijections
between cluster variables, almost positive roots and positions in the word Qc.
Sundaram described Sun as the composition of several bijections
In this paper, we clarify the relationship between two algorithmic bijections
, due respectively to Edelman and Greene (1987) and to Little (2003), both of which deal with reduced decompositions in the symmetric group, [S.
25]), which leads to functional equations for generating functions of maps, to the beautiful bijections
initiated by Schaeffer  and further developed by physicists and combinatorics alike [5, 9], via a powerful approach based on matrix integrals .

BORED with separating sets of numbers into piles of bijections
and Cayleigh tables, this weekend, I took to rummaging through a seldom opened cupboard.
The set SYM(G,*) = SYM(G) of all bijections
in G forms a group called the permutation (symmetric) group of G.
Morphisms between A-weighted sets are weight preserving bijections
From the presented details it does not follow that Bohr's complementarity principle is wrong, we have just explicitly reformulated the principle providing strict definitions for which way claims as bijections
, and have clarified the useful terms self-interference and cross-interference.
We succeed in providing bijections
for the drop function (Theorem 3.
The set I (X) is a semigroup where the product of two such bijections
is just composition, defined where it makes sense.
