Barrie Gunter,Anders Hansen,Maria Touriets are well-known two-dimensional surfaces like the Euclidean plane, the real projective plane, the sphere, the torus, and the cylinder. Their lines, blocks, or circles are curves that are nicely embedded in these surfaces. Usually these curves will be homeomorphic to the real line or to the unit c荧光 发表于 2025-3-27 03:44:28
