使用する際の注意点

• For the most part, map and function are synonyms in mathematics, and are frequently used interchangeably; however, certain branches of mathematics sometimes use map in a specialised sense to mean a function that preserves some important property in that branch of mathematics, i.e. a morphism. For instance, in topology, map may specifically mean a continuous function, and in linear algebra it may specifically mean a linear transformation.
