負元素個數性

+1  

少於0個元素的數學集合屬性(就像物理學中的反物質。)

YAML 來源 想法

負數和虛數的發明被證明對數學很有用。然而,集合運算並沒有少於0個元素的概念。我們到達空集 {},然後就停止了,但爲什麼要這樣呢?想象一個屬性:減去一個不在集合中的元素,會產生一個消滅該元素的潛力。這種潛力可以標記爲帶有撇號的元素。即,{1,2',2} = {1}。

這個想法是受“世界上最獨特的俱樂部”的啓發,在思考超級排他性的時候。

負基數是某種東西的赤字,一項尚未完成的任務。它與順序、然後和時間有關。非常有意思

Negative cardinality is deficit of something, a task yet to be done. It has to do with sequence, then, and time. Really interesting

skihappy,

是的,也許它可以簡化會計,或者它甚至可以幫助使目標追求更加想象,因爲所有形式化爲一組...... /github.com/wefindx/asterisk/blob/master/docs/2016-09-28_Goals_are_Just_Assets.md

Yeah, perhaps it could simplify accounting, or maybe, it could even help make goal-pursuit more imaginary, as everything that's formalized as a set of sets of ... of sets, could suddenly have that imaginary component ("goals are just imaginary assets").
