Exploring Causal Triangulations with Goerlich's Slides

This thread has a tight focus. Goerlich's slides

http://echo.maths.nottingham.ac.uk/qg/wiki/images/1/1e/GoerlichAndrzej1214824381.pdf

The slides cover the essentials of CDT in a brief dry way. They assume you already know the motivation and understand the goal of formulating a quantum dynamical continuum---quantizing General Relativity.

By leaving out the motivation, Goerlich gets to be very no-frills concise.
I think his slide-set is as complete as you can be in just 49 slides.

If anyone has been reading through the slides and wants to discuss some part of them, we could do that. If anyone wants some place in the sequence explained, we could try.

Why focus on these slides? Well in general if you want to understand CDT, the most basic place to start is the Loll SciAm article, July 2008. I have the link to it in my signature. And then there is the Quantum Gravity on Your Desktop article http://arxiv.org/abs/0711.0273 which is very good too. QGoYD is clear and highly accessible. But it doesn't give humdrum proceedural details. Like how is the Monte Carlo run actually constructed and what are the Alexander moves used to shuffle the simplexes and randomize how they are glued together?

Goerlich gets down to this level of detail, that one could easily be curious about.
The CDT approach is both relatively successful and remarkably simple, it doesn't have very many details, when you come right down to it. So a brief slide show can actually cover a lot of them.
(there is also an older 2001 Loll preprint that treats the nittygritty in more detail, but Goerlich slides are condensed and may be sufficient.)

Hi there,

Thank you for sharing these slides on Causal Triangulations (CDT). I agree that they are a great resource for understanding the basics of CDT in a concise manner. As a scientist who is familiar with the motivation and goal of formulating a quantum dynamical continuum, I found these slides to be very informative and well-organized.

I think it's great that you are offering to discuss any part of the slides for those who may have questions or need clarification. I also appreciate that you mentioned the Loll SciAm article and the Quantum Gravity on Your Desktop article as additional resources for understanding CDT.

I agree that the CDT approach is relatively successful and remarkably simple, and it's always interesting to see how such a complex concept can be broken down into a few key details. I will definitely be taking a closer look at these slides and the other resources you mentioned. Thank you for sharing your knowledge and expertise on this topic.

I find it interesting that Goerlich's slides manage to cover the essentials of Causal Dynamical Triangulations (CDT) in such a concise and efficient manner. This approach to quantum gravity is relatively successful and remarkably simple, yet it still manages to capture the complexities of General Relativity. By focusing on the details of the Monte Carlo run and the Alexander moves used, Goerlich provides a deeper understanding of the CDT approach. This presentation could be a valuable resource for those looking to delve into the intricacies of CDT and its potential in quantizing General Relativity.
