For example,Set A = { 8 } is a singleton set. 3. Finite and Infinite Sets A set that has a finite number of elements is known as a finite set, whereas the set whose elements can't be estimated, but has some figure or number, which is large to precise in a set, is known as ...
称 A 是\mathcal{C} 中的“单点对象 (singleton object)”,如果 A 不是initial object,且对任何 \mathcal{C} 中的非initial的object B 及任何morphism f:B\to A ,都有 f 是epimorphism. 注意到 在范畴 \mathbf{Set} 中,一个object是由一个元素组成的集合 * 当且仅当它是单点对象....
1. Singleton Set If a set contains only one element it is called to be a singleton set. Hence the set given by{1}, {0}, {a}are all consisting of only one element and therefore are singleton sets. 2. Finite Set A set consisting of a natural number of objects, i.e. in which nu...

Figure 2.5.The relation between shared and out-of-process dependencies. An example of a dependency that is shared but not out-of-process is a singleton (an instance that is reused by all tests) or a static field in a class. A database is shared and out-of-process—it resides outside...

A set-theoretic account allows the word 'theory' (like 'set') to be used for fields and families (T and , with many elements) as well as individual theories (θ , which may be singleton sets, consisting of a single journal article). The- ory, denoted by θ , , and T, can be ...
