Cone in topological space Homotopy problem

In summary, the conversation discusses the concept of homotopy in relation to continuous functions in a topological space, specifically in the cone of a given space. The homework problem asks to show that any two continuous functions in this cone are homotopic, and also to find the fundamental group of the cone. The student is seeking hints or help in solving the problem, and the expert suggests considering a special function and using the composition of homotopies. Additionally, part (b) is a simple result of part (a).

Homework Statement



Let Y be a topological space. Let CY denote the cone on Y.

(a) Show that any 2 continuous functions f, g : X --> CY are homotopic.
(b) Find (pi)1 (CY, p).

Homework Equations



I have no idea. The professor said one problem would be way out in left, to see who could make the connections. I can't. lol

The Attempt at a Solution



See 2.!

I know I haven't made an attempt, so I'm not asking for an answer. Any hints or help is much appreciated.

Remember that if two functions [tex]f, g[/tex] are each homotopic to another function [tex]k[/tex], then you can compose the homotopies to see that [tex]f[/tex] is homotopic to [tex]g[/tex]. Keeping that in mind, can you find a function [tex]k: X \to CY[/tex] which is special somehow, and useful for making homotopies in this way?

Part (b) is an easy corollary of part (a).
 

1. What is the cone in topological space homotopy problem?

The cone in topological space homotopy problem is a mathematical problem that involves studying the properties of a cone-like space in relation to continuous deformations, or homotopies, of the space. This problem is important in topology, which is a branch of mathematics that studies the properties of geometric objects that remain unchanged under continuous deformations.
