Coarse function

In mathematics, coarse functions are functions that may appear to be continuous at a distance, but in reality are not necessarily continuous.Chul-Woo Lee and Jared Duke (2007), Coarse Function Value Theorems. Rose-Hulman Undergraduate Mathematics Journal 8 (2) Although continuous functions are usually observed on a small scale, coarse functions are usually observed on a large scale.
