Algebraic topology

James reduced product

In topology, a branch of mathematics, the James reduced product or James construction J(X) of a topological space X with given basepoint e is the quotient of the disjoint union of all powers X, X2, X3, ... obtained by identifying points (x1,...,xk−1,e,xk+1,...,xn) with (x1,...,xk−1, xk+1,...,xn). In other words, its underlying set is the free monoid generated by X (with unit e). It was introduced by Ioan James. For a connected CW complex X, the James reduced product J(X) has the same homotopy type as ΩΣX, the loop space of the suspension of X. The commutative analogue of the James reduced product is called the infinite symmetric product. (Wikipedia).

Learn how to determine the product of two fractions with unlike denominators

👉 Learn how to multiply fractions. To multiply fractions, we need to multiply the numerator by the numerator and multiply the denominator by the denominator. We then reduce the fraction. By reducing the fraction we are writing it in most simplest form. It is very important to understand t

fg is continuous

Here I show that the product of two continuous functions is continuous. I do it both by using epsilon-delta and the sequence definition of continuity. Interestingly, the proof is similar to the proof of the product rule for derivatives. Enjoy! Product of limits: https://youtu.be/4pvFRvtMq

How to determine the scale factor for the dilation of two triangles

👉 Learn about dilations. Dilation is the transformation of a shape by a scale factor to produce an image that is similar to the original shape but is different in size from the original shape. A dilation that creates a larger image is called an enlargement or a stretch while a dilation tha
