I Is √9x a Bijection from N to R? Let f : N −→ R and f(x) = √ 9x The domain is all natural numbers: {0, 1, 2, 3, ...} The codomain is all real numbers. The range i believe is [0, +infinity) I believe that although the above is a function since every input ...
A provably correct bijection between higher-order abstract syntax (HOAS) and the natural numbers enables one to define a ``not equals'' relationship between terms and also to have an adequate encoding of sets of terms, and maps from one term family to another. Sets and maps are useful in ...
In the recent decades, core partitions and bar core partitions have attracted much attention from combinatorial researchers. In this paper, we build a bijection between-cores and self-conjugatet-cores for odd integers. To this end, we first establish a bijection between-cores and self-conjugate-...
A natural question arises of a bijective proof for this formula [14]. The problem is to define a correspondence between spanning trees and orientations, preserving parameters (i,j), called activities in the literature, and compatible with the above formula. More precisely, the desired ...
Baxter numbers are known to count several families of combinatorial objects, all of which come equipped with a natural involution. In this paper, we add a combinatorial family to the list, and show that the known bijections between these... K Dilks 被引量: 6发表: 2015年 Polynomial endomorph...
