👉 In mathematics, a deuteromorphism is a function that can be defined on an object with two or more arguments. The term "deuteromorphic" refers to the property of being able to be inverted as its argument changes. For example, consider a function f(x) = x^2 - 1. If we define a deuteromorphism g(y) = y^2 + 1 for all y in the domain of f, then g is called a deuteromorphic function
