monotonic mapping
A mathematical term for a mapping that preserves order. Related to 単調関数 (monotonic function).
See also: 単調関数
This monotonic mapping preserves order.
単調関数 is a monotonic function, while 単調写像 is a more general monotonic mapping between ordered sets.
Compound of 単調 (monotone) and 写像 (mapping). The exact historical derivation is uncertain; the term is a modern mathematical coinage.
