In topology, being able to decompose manifolds into simplicial complexes is of great importance to better study their properties. As such, it is vital that techniques be developed to compute topological invariants between different manifolds. This project will attempt to examine a property known as Grunbaum coloring, and determine when one can find such a coloring given a triangulation of a manifold. It is known when Grunbaum coloring exist for the torus, sphere, and projective plane, but more work can be done on 3-manifolds or surfaces of genus 4 and greater. The results from this research may have implications in graph theory or computations involving triangulations, as homeomorphisms are more easily computable.

Unfortunate Discovery
May 1, 2023
Error With Counterexample Last week, I proposed an potential graph that would improve a bound on Grunbaum’s conjecture. However, I now see that I missed a defect on the inside of the embedding. Unfortunately, it doesn’t look like this will be easy to fix, so I’m going to dedicate the coming week reading more papers […]

Improving A Counterexample To Grunbaum’s Conjecture
April 24, 2023
We left off last time with the possibility of exploring a new family of graphs. Unfortunately, computer computation of edge colorability revealed that it was not a snark. However, this week marks an incredible discovery that, if correct, should disprove Grunbaum’s Conjecture for all surfaces of genus at least 3. Constructing The Counterexample My work […]

Exploring New Graphs
April 17, 2023
We are now officially halfway through to the end of the project! Construction Of The New Graph Last week, I left off in favor of a more theoretical approach, and would like to introduce one of the graphs I found. In Belcastro’s paper “Families of Dot-Product Snarks on Orientable Surfaces of Low Genus,” two families […]

More Progress On The Code
April 9, 2023
Welcome back to the fifth blog in my adventure with graphs. Previous Goals Last time, I left off with proposing two new features to add to my code: the ability to compute dot products and the ability to compute defects. I am happy to say that I have accomplished both these goals. The dot product […]
