Homework Help Overview

The discussion revolves around identifying an example of a non-homogeneous topological space. Participants are exploring the concept of spaces that exhibit different topological properties in various regions.

Discussion Character

  • Exploratory, Conceptual clarification

Approaches and Questions Raised

  • Participants are attempting to conceptualize non-homogeneous spaces and are discussing the idea of using the real line with varying metrics in different segments as a potential example. Questions arise regarding the validity of these proposed metrics in relation to the definition of a non-homogeneous topological space.

Discussion Status

The discussion is ongoing, with participants sharing their thoughts and questioning the appropriateness of suggested examples. There is an exploration of different interpretations of what constitutes a non-homogeneous space, and some guidance is being offered regarding the nature of metrics.

Contextual Notes

Participants are grappling with the definitions and properties of topological spaces and metrics, which may be contributing to the difficulty in identifying a suitable example. The original poster expresses uncertainty about where to begin, indicating a potential gap in foundational understanding.

I'm asked to find an example of a non-homogeneous topological space. To be honest I'm not really sure where to get started. Intuitively I think I'm looking for a space where one part of it has different topological properties from another location. I just can't think of a well-known space for which this would be true.

What difficulty are you having translating this into an example? Just pick the parts and put them into a space.
 
so could i pick say the real line [itex]\mathbb{R}[/itex] as my space but with different metrics in different parts

i.e.

[itex]\forall x \geq 0, d(x,y)=x-y[/itex]

[itex]\forall x<0, d(x,y) = x+y[/itex]

or something like that?
 
i don't know about the non-homogenous topological space part, but i don't think that's a metric
