definition

A topological space which is a product of two circles.

example

A 4-variable Karnaugh map can be thought of, topologically, as being a torus.

definition

The standard representation of such a space in 3-dimensional Euclidean space: a shape consisting of a ring with a circular cross-section: the shape of an inner tube or hollow doughnut.

definition

(in combination, n-torus, 4-torus, etc.) The product of the specified number of circles.

definition

A molding which projects at the base of a column and above the plinth.

definition

The end of the peduncle or flower stalk to which the floral parts (or in the Asteraceae, the florets of a flower head) are attached; receptacle, thalamus.

definition

A rounded ridge, especially one on the occipital bone.

The enlarged torus covering the ovary.

The columns have marked entasis, and the flutings end in a semicircle, above which is generally a torus (always present in the so-called temple of Ceres).

A similar band of ornament runs round the top of the walls outside, and at their base is a reeded torus.

The termination of the peduncle, or the part on which the whorls of the flower are arranged, is called the thalamus, torus or receptacle.

The axis is usually very much contracted, no internodes being developed, and the portion bearing the floral leaves, termed the thalamus or torus, frequently expands into a conical, flattened or hollowed expansion; at other times, though rarely, the internodes are developed and it is elongated.

Many AGN also show evidence for a huge torus of gas around the black hole.

As an example let 's define a torus the hard way.

Upon this torus the parts of the flower are arranged in a crowded manner, usually forming a series of verticils, the parts of which alternate; but they are sometimes arranged spirally especially if the floral axis be elongated.

The stamens arise from the thalamus or torus within the petals, with which they generally alternate, forming one or more whorls, which collectively constitute the androecium.

It may consist of processes rising from the torus, alternating with the stamens, and thus representing an abortive whorl; or its parts may be opposite to the stamens.

When in a compound pistil the style of each carpel is thus displaced, it appears as if the ovary were depressed in the centre, and the style rising from the depression in the midst of the carpels seems to come from the torus.

It also strips some material away from Io which forms a torus of intense radiation around Jupiter.

Here is a two dimensional slice through the Teichmüller space of the twice punctured torus drawn with some of the pleating rays.

As an example let's define a torus the hard way.

What is the nature of the massive dusty torus believed to surround Active Galactic Nuclei?

Agents were located on a two-dimensional torus and were given resources to exchange with other agents.

The liquid wall can conceivably be applied to future magnetic fusion reactors, whether a spherical torus, a tokamak, or another design.

Based on rather circumstantial evidence, jets are thought to emerge from the AGN at right angles to the dust torus.

This material becomes ionized in the magnetic field and forms a doughnut-shaped cloud of intense radiation referred to as a plasma torus.

The world is no longer a plane torus, its boundaries are not connected.

Expectation level E = 30 %, Initial cluster of 9 × 9 = 81 contributors, 50 × 50 torus grid.
