Codomainista

Codomainista is a term sometimes used within discussions of mathematics, particularly in set theory and functional analysis, to refer to a concept related to the codomain of a function. It is not a formally established or widely recognized mathematical term with a precise definition. Instead, it appears to be an informal or colloquial descriptor, often used humorously or by a small group of individuals.

The term likely derives from "codomain," which is the set into which all the output of a function is constrained to fall. A "codomainista" might therefore be someone who places a particular emphasis on the codomain in their mathematical reasoning or who is particularly interested in the properties and implications of the codomain of a function. This could manifest as focusing on surjective functions, where the codomain is fully "hit" by the function's outputs, or exploring different codomains for the same function to alter its properties. However, without a formal definition, the precise meaning remains subjective and dependent on the context in which the term is used.
