My question is: what are some examples of these results, and where can a more thorough explanation of why this is the case be found?



Results in computational geometry utilizing doubling dimension of a metric space
The question is a bit unclear, so I'm not sure this is what you seek.
But here is a connection to computational geoemtry.


There is considerable literature on
[geometric spanners](https://en.wikipedia.org/wiki/Geometric_spanner) and [doubling metric spaces](https://en.wikipedia.org/wiki/Doubling_space).
Here is a sampling of references from 2006, 2008, 2019, 2022. And from their references you can locate many more.
