WebMODULI OF SPHERICAL VARIETIES AND LOG GOEOMETRY MARTIN OLSSON Abstract. We give moduli interpretations using log geometry of the main components of the moduli spaces of polarized In geometry, a torus (plural tori, colloquially donut or doughnut) is a surface of revolution generated by revolving a circle in three-dimensional space about an axis that is coplanar with the circle. If the axis of revolution does not touch the circle, the surface has a ring shape and is called a torus of revolution. If … Zobraziť viac A torus can be defined parametrically by: • θ, φ are angles which make a full circle, so their values start and end at the same point, • R is the distance from the center of the tube to the center of the torus, Zobraziť viac The torus has a generalization to higher dimensions, the n-dimensional torus, often called the n-torus or hypertorus for short. (This is the more typical meaning of the term "n-torus", the other referring to n holes or of genus n. ) Recalling that the torus is the … Zobraziť viac In the theory of surfaces there is another object, the "genus" g surface. Instead of the product of n circles, a genus g surface is the connected sum of g two-tori. To form a connected sum of two surfaces, remove from each the interior of a disk and "glue" the surfaces … Zobraziť viac Topologically, a torus is a closed surface defined as the product of two circles: S × S . This can be viewed as lying in C and is a subset of the 3-sphere S of radius √2. This topological torus … Zobraziť viac The 2-torus double-covers the 2-sphere, with four ramification points. Every conformal structure on the 2-torus can be represented as a two-sheeted cover of the 2-sphere. The points on the torus corresponding to the ramification points are the Zobraziť viac A flat torus is a torus with the metric inherited from its representation as the quotient, $${\displaystyle \mathbb {R} ^{2}}$$/L, … Zobraziť viac Polyhedra with the topological type of a torus are called toroidal polyhedra, and have Euler characteristic V − E + F = 0. For any number of holes, the formula generalizes to V … Zobraziť viac

WebWhen gravity clumps stuff (like tons of hydrogen space dust, and even crazier space dust) together in a nebulae like the Orion Nebula, you get stars. Other nebulae are super nice remnants, like the ring and dumbbell nebulas, so they were formed when a star exploded at the end of its life cycle. Iirc those are actually torus-shaped (aka donut ... Web31. jan 2024 · We apply the GBT and show that the surface topology at the wormhole throat is indeed a torus by computing the Euler characteristic number. As a special case of the ringhole solution, one can find the Ellis wormhole which has the surface topology of a 2-sphere at the wormhole throat. ... It is found that the spherical wormholes are stable ...
