👉 In mathematics, a stalk is a type of object that can be seen as an extension of a topological space. It represents a set of points or values in a space, and it allows us to think about how these values change from point to point. For example, consider the real line R with its usual topology. We can define a stalk on this line by considering the collection of all functions f: [0, 1] -> R that are continuous at x = 0 (i
