👉 In mathematics, a joinable function is a function that can be represented by a finite sequence of sets. These functions are typically used in mathematical analysis and topology to describe continuous transformations between topological spaces. A joinable function satisfies certain properties such as being bounded (continuous), Lipschitz continuous, and having a compact inverse. For example, consider the function f(x) = x^2 on the interval [0, 1]. This function is not necessarily a joinable function because it does
