The Curvature of graphs multplies under the Shannon product (strong product).
A few more remarks [PDF] about graph arithmetic. Now on the ArXiv. (Previous documents are here (June 2017 ArXiv), here (August 2017 ArXiv) and here (May 2019 … ….
Last summer I have had some fun with codimension 2 manifolds M in a purely differential geometric setting: a positive curvature d-manifold which admits a circular action … ….
Last week, I practiced a bit more enhanced talk presentation style in which, rather than with slides, the content is spoken and then enhanced in the video … ….
10 theorems about discrete manifolds were featured in a youtube video.
The problem of discretization It is a question which probably was pondered first by philosophers like Democrit or Archimedes. What is the nature of space? It is … ….
We prove that connected combinatorial manifolds of positive dimension define finite simple graphs which are Hamiltonian.
