Loop (topology)

In mathematics, a loop in a topological space X is a continuous function f from the unit interval I = [0,1] to X such that f(0) = f(1). In other words, it is a path whose initial point is equal to its terminal point. A loop may also be seen as a continuous map f from the pointed unit circle S1 into X, because S1 may be regarded as a quotient of I under the identification of 0 with 1. The set of all loops in X forms a space called the loop space of X. (Wikipedia).

JavaScript Lingo: Loops

Basic intro to answer the question, "What's a Loop?" If there's a set of data, (we'll use an array for this example, but it doesn't have to be,) and you want to perform the same manipulation to every piece in that set of data, you can use something called a loop. Loops have some complex

Overview of Loops in Graph Theory | Graph Loop, Multigraphs, Pseudographs

What are loops in graph theory? Sometimes called self loops, a loop in a graph is an edge that connects a vertex to itself. These are not allowed in what are often called "simple graphs", which are the graphs we usually study when we begin studying graph theory. In simple graphs, loop ed

What is a closed set ?

I define closed sets, an important notion in topology and analysis. It is defined in terms of limit points, and has a priori nothing to do with open sets. Yet I show the important result that a set is closed if and only if its complement is open. More topology videos can be found on my pla
