U+2294 Square Cup

U+2294 was added in Unicode version 1.1 in 1993. It belongs to the block U+2200 para U+22FF Mathematical Operators in the U+0000 para U+FFFF Basic Multilingual Plane.

This character is a Puntuación matemática and is commonly used, that is, in no specific script.

The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+2294 forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph.

El Wikipedia tiene la siguiente información acerca de este punto de código:

In mathematics, the disjoint union (or discriminated union) A B of the sets A and B is the set formed from the elements of A and B labelled (indexed) with the name of the set from which they come. So, an element belonging to both A and B appears twice in the disjoint union, with two different labels.

A disjoint union of an indexed family of sets ( A i : i I ) is a set A , often denoted by i I A i , with an injection of each A i into A , such that the images of these injections form a partition of A (that is, each element of A belongs to exactly one of these images). A disjoint union of a family of pairwise disjoint sets is their union.

In category theory, the disjoint union is the coproduct of the category of sets, and thus defined up to a bijection. In this context, the notation i I A i is often used.

The disjoint union of two sets A and B is written with infix notation as A B . Some authors use the alternative notation A B or A B (along with the corresponding i I A i or i I A i ).

A standard way for building the disjoint union is to define A as the set of ordered pairs ( x , i ) such that x A i , and the injection A i A as x ( x , i ) .
