若有一函數 f 代表 X→Y,則其反函數 f⁻¹ 就是 Y→X,可以有反函數的函數稱為「可逆函數(invertible function)」,所有可逆函數必為雙射函數。 在下圖中,f(x) 與 f⁻¹(x) 互為反函數關係、g(x) 與 g⁻¹(x) 亦互為反函數關係。對於 f(x) 及 g⁻

degree functionswitch operationsWeak immersion is a generalization of the immersion relation defined by Nash-Williams. A graph H is said to be weakly immersed in a graph G if H can be obtained from G by a sequence of these three operations: taking a subgraph, splitting a vertex, and ...
这道题 我给你一个肯定不会错的回答 我先告诉你一下区别 the relation is a function since no two different ordered pairs the same x-coordinate 问题你可以稍微修改上面的回答 或者你也可以说 a function is a relation in which 2 different ordered pairs have the same x- coordinate.结果...
一个mapping/transformation/function定义为\(T:X\mapsto Y\),这是一种将\(X\)中的每个元素与\(Y\)中唯一一个元素联系起来的规则。\(X\)称为domain(定义域),\(Y\)为codomain(到达域),集合\(G_T=\{(x,y):x\in X,y=T(x)\}\subseteq X\times Y\)称为graphof \(T\)。集合\(T(A)=\{T...
A graph G is called edge-magic if there is a bijective function f from the set of vertices and edges to the set {1,2,…,|V(G)|+|E(G)|} such that the sum f(x)+f(xy)+f(y) for any xy in E(G) is constant. Such a function is called an edge-magic labeling of G, and...

It additionally enables the application of automatic theorem proving; see [9], [13] for examples, where Prover9 is used to verify some graph algorithms that are formulated by means of programs operating on relations as data.If we assume a function rectangle...
Specific predictions about the relations of size, spatial position, and identity analyses were made; further, these predictions differed as a function of stimulus parameters. Twenty-four Ss were tested on a task designed to reveal relations among various analyses. The results supported the contention...
