I am a beginner in network topology topics and while I was reading an article about simplicial complexes where the authors had used random simplicial complexes, I came across a formula using "average degree of a d-simplex". I have been looking at other articles online but I couldn't get a simple definition. I was wondering if anyone could help me understand what is the average degree of a d-simplex? Does it exist for all simplicial complexes (both random and not random)? How do we calculate it?
Any help on finding the answer to these questions is very appreciated!
