#mathematics A function whose domain is a subset of some set
Usage notes
This is not a formal term, but a metamathematical description which only assumes concrete meaning in context. For example, in computability theory, a partial function is a function whose domain is a subset of <math>{\N}^k</math> for some k, but in other fields the term has other meanings.
