A free ring satisfies the universal property: any function from the set X to a ring R factors through F so that F → R is the unique ring homomorphism. Just as in the group case, every ring can be represented as a quotient of a free ring. [46] Now, we can impose relations among symbols in X by taking a quotient.
The rings of Neptune are made of extremely dark material, likely organic compounds processed by radiation, similar to those found in the rings of Uranus. [ 5] The proportion of dust in the rings (between 20% and 70%) is high, [ 5] while their optical depth is low to moderate, at less than 0.1. [ 6] Uniquely, the Adams ring includes five ...
Therefore, the class of all rings together with ring homomorphisms forms a category, the category of rings. The zero map R → S that sends every element of R to 0 is a ring homomorphism only if S is the zero ring (the ring whose only element is zero). For every ring R, there is a unique ring homomorphism Z → R.
Formally, a unique factorization domain is defined to be an integral domain R in which every non-zero element x of R can be written as a product of a unit u and zero or more irreducible elements pi of R : x = u p1 p2 ⋅⋅⋅ pn with n ≥ 0. and this representation is unique in the following sense: If q1, ..., qm are irreducible elements of R ...
The ε ring is the brightest and densest part of the Uranian ring system, and is responsible for about two-thirds of the light reflected by the rings. [12] [21] While it is the most eccentric of the Uranian rings, it has negligible orbital inclination. [23] The ring's eccentricity causes its brightness to vary over the course of its orbit.
The F Ring is the outermost discrete ring of Saturn and perhaps the most active ring in the Solar System, with features changing on a timescale of hours. [132] It is located 3,000 km (2000 miles) beyond the outer edge of the A ring. [133] The ring was discovered in 1979 by the Pioneer 11 imaging team. [80]
