Disjunkteja

Disjunkteja is a term used in mathematics, specifically in set theory and logic. It refers to two or more sets that have no elements in common. In other words, their intersection is the empty set. For example, if set A contains {1, 2, 3} and set B contains {4, 5, 6}, then A and B are disjunkteja because there is no number that is present in both sets. The concept of disjunkteja is fundamental to understanding various mathematical structures and operations.

In logic, disjunkteja can also refer to propositions or statements that cannot both be true simultaneously. If two statements are disjunkteja, then the truth of one implies the falsity of the other. This is closely related to the logical operator "XOR" (exclusive OR), which is true only when exactly one of its operands is true. The idea of disjunkteja is important in fields like probability theory, where mutually exclusive events are those that cannot occur at the same time.
