Discussion Overview

The discussion centers around the concept of a bifurcation diagram, particularly in the context of non-linear functions and its relevance to chaos theory. Participants explore how to create such diagrams and their applications, including potential connections to differential equations.

Discussion Character

  • Homework-related
  • Exploratory
  • Technical explanation

Main Points Raised

  • One participant requests an explanation of what a bifurcation diagram is and how to create one, indicating urgency due to an upcoming exam.
  • Another participant reflects on missing the discussion and suggests that bifurcation diagrams are significant in chaos theory, alongside other concepts like the Mandelbrot Set and Lorenz attractor.
  • A participant shares a bifurcation diagram for the logistic map and mentions the possibility of creating more detailed diagrams using programming languages like C++, while also expressing uncertainty about the connection to differential equations.
  • There is a suggestion for collaboration on generating bifurcation diagrams, with a humorous acknowledgment of the summer break affecting participation.

Areas of Agreement / Disagreement

Participants express varying levels of familiarity with bifurcation diagrams, and while some share resources and ideas, there is no consensus on the specifics of their creation or the extent of their applications.

Contextual Notes

There are unresolved questions about the relationship between bifurcation diagrams and differential equations, as well as the technical details of generating these diagrams using different software.

Could some explain or point me to somewhere explains what a Bifurcation Diagram is and how to draw one given a non-linear function. Got an exam today and nobody knows what one is. If it has already been 2 hours after I've posted this don't worry, I'll be heading off to the exam hehe. Thanks if anyone can give any help.

Too late now, thanks if anyone tried to look something up.

Jesus Zurtex. I'm a day late and a dollar short, alright 5 whatever. Wish I would have seen this but I was away for awhile. Has a bifurcation diagram ever been presented in the forum? You know it's one of the three icons of Chaos Theory right? You know, Mandelbrot Set, Lorenz attractor, Feigenbaum plot (bifurcation diagram). We should post one. Well me if you don't feel like it. In fact, since we have three spaces down there, we should post all three. Dude, you're long gone with this aren't you.
 
Attached is the bifurcation diagram for the logistics map. You can make a much more detailed one using C++ but I can't convert it to JPEG so I have to use Mathematica.

I suppose it is relevant to differential equations since bifurcation diagrams can also be created for differential equations (pretty sure anyway, need to check). Zurtex, wanna' generate one for such? I suspect I know what you're thinking, "dude, I ain't generating nothin', it's summer time". :smile:
