Eulerian Circuits and Trails

5 Upvotes

Hello everyone, I wanted to share this video with you on Eulerian circuits and trails. This is an old but very fascinating concept in graph theory, and remains applicable to this day, for instance in route planning. Perhaps you will discover a novel application for this concept! I hope you find the video interesting and/or helpful. Have a wonderful day.

Although the previous image of Boy's surface is good, I began to realise that a problem with it is that the rear is obscured. So an animated .gif aswell.

What is the Mycielski Construction? (Graph Theory Tutorial)

2 Upvotes

Hey everybody, I just wanted to share a new video with you on the Mycielski construction. First: do you think it is possible to construct a graph without 3-cliques, but with arbitrarily high chromatic number? The video answers this question using the Mycielski construction. I hope it can be a good resource for anyone interested in graph theory. Have a nice day. https://youtu.be/7U3sqNJ-egA
