Korresponderande

Korresponderande is a Swedish adjective meaning that two or more things correspond to each other according to a defined relation. The term is used across disciplines to describe a pairing that is established by rules or a recognized connection, rather than by coincidence. It is common in mathematics, linguistics, and information science.

In mathematics, a korresponderande relation between two sets A and B relates elements a in A to elements b in B. If each element a has exactly one associated element b, the relation is a function. If, in addition, every b is associated with exactly one a, the relation is bijective and forms a perfect korresponderande pairing. In geometry and mapping contexts, corresponding points or features are those matched under a transformation, such as a reflection or projection.

In linguistics and lexicography, korresponderande items are translation equivalents in different languages that carry the same meaning or usage. In data integration and information systems, korresponderande fields or variables are those that align across schemas or datasets, enabling data to be combined, compared, or migrated consistently.

The concept emphasizes formal or rule-based matching rather than mere similarity. Related terms include korrespondens, meaning correspondence, and correspondens, used in similar sense in various technical contexts.
