Poloidal direction (red arrow) and toroidal direction (blue arrow) A torus of revolution in 3-space can be parametrized as: [2] (,) = (+ ) (,) = (+ ) (,) = using angular coordinates θ, φ ∈ [0, 2π), representing rotation around the tube and rotation around the torus's axis of revolution, respectively, where the major radius R is the distance from the center of the tube to ...
Antoine Song (born 18 July 1992 in Paris) is a French [1] mathematician whose research concerns differential geometry. In 2018, he proved Yau's conjecture. He was a Clay Research Fellow (2019–2024). [2] He obtained his Ph.D. from Princeton University in 2019 under the supervision of Fernando Codá Marques. [3]
In mathematics, a toroid is a surface of revolution with a hole in the middle. The axis of revolution passes through the hole and so does not intersect the surface. [1] For example, when a rectangle is rotated around an axis parallel to one of its edges, then a hollow rectangle-section ring is produced.

This illustrates that a coffee mug and a donut are homeomorphic. In mathematics and more specifically in topology , a homeomorphism ( from Greek roots meaning "similar shape", named by Henri Poincaré ), [ 2 ] [ 3 ] also called topological isomorphism , or bicontinuous function , is a bijective and continuous function between topological spaces ...
