Definition: Haskness is a mathematical concept in algebraic topology, specifically in the theory of manifolds. It is used to describe how certain types of maps behave under various operations on a manifold. In the context of algebraic topology, Haskness refers to the behavior of certain kinds of maps between manifolds. These maps are often defined by specifying how they "interact" with each other or with their inputs and outputs. For example, two maps can have different properties depending on which
