May I ask what are the relations between the geometry and combinatorics near a torus fixed point? Any references? In particular, let $ S$ be a scheme that is torus invariant with finitely many zero and one dimensional orbits. What can you say about the singularity at a fixed point if the number of torusRead more

I’m trying to draw the $ K6$ graph on a torus. I plotted and the torus and the six points, and I know how to parametrize a path in $ \mathbb{R}^{3}$ from each point to another. However, I can’t figure out how to take these paths and make them stay along the surface of theRead more
