What Are Rings?
What Are Rings?
Rings are mathematical structures that generalize and emulate familiar properties of integer addition and multiplication. They are also the basis for many of the facts and techniques that appear in other areas of math.
A ring is a circular band of metal worn on the fingers, and sometimes the toes or through piercings in the ears or nose. They have long been used to symbolize authority, fidelity and social status.
Definition
A ring is a set of mathematical elements that is commutative under addition and associative under multiplication. In other words, it is a mathematical structure that can be generated by taking the products of elements in the ring, as defined by axioms such as: (a + b) = ab and ab = a+b. In particular, the ring of integers is a ring, as are all prime numbers and their squares.
A ring can also refer to:
1. a circular band of precious metal worn on the finger as an ornament or symbol of betrothal or marriage. 2. a group of people or things arranged in a circle: The prisoners were jewelry wholesale ringed with guards. 3. a circular movement or course: They danced in the ring. 4. an enclosed area, usually circular, in which sports contests or exhibitions take place: A ring for boxing and wrestling.
Some authors depart from the normal convention and define rings to include more general structures, in which it is not necessary that multiplication be associative. For these authors, all algebraic structures are rings. However, most ring theory is based on the notion of a commutative ring with a non-associative multiplication. In particular, a ring has a left zero divisor if there exists a positive integer a such that aa+a=0. In the case of an a-ring, the left zero divisor is the identity element.
Origin
Rings have been worn as symbols of love, loyalty and friendship in many cultures throughout history. Their origins are as diverse as the people who wear them, from the ancient Egyptian woven rings to the modern rings worn through piercings in the nose and ears.
The earliest existing rings are from ancient Egypt, where they were primarily used as signets or talismans. These were carved with the name and titles of the owner in hieroglyphics on an oblong gold bezel. The ancient Greeks were more likely to use rings for decorative purposes, but the Romans embraced them as a mark of status and wealth.
By the Middle Ages, the number of ring designs had grown immensely. The most popular were the gimmel rings, which were made from interlocking rings of different metals. The rings were sometimes adorned with gemstones or even miniature houses. Other rings were engraved with romantic messages. These were often inscribed with words of love or a pledge of affection, such as the French phrase “pense de moi” (“think of me”).
The term “ring” also came to refer to a multiplicative identity (i.e., property 8), which is a special case of the general cyclotomic property of integers. This is probably because of the early association of ring-shaped numbers with the mathematical concept of a ring.
Meaning
In mathematics, a ring is a set of elements with a multiplicative identity. A ring is called commutative if every nonzero element has a multiplicative inverse as well. gold plated earrings Commutative rings are important in number theory and algebraic geometry.
A ring can also be used as an ornament or symbol of marriage or commitment. It can be worn on the left or right hand, or it may be put around an object such as a tree or rock. In some cultures, men wear rings on their thumbs to signify their boldness and strength.
The term ring can also refer to an idea or opinion that seems familiar. For example, his proud boast that he leads the party of low taxation has a ring to it. She was jolted out of her sleep by the ringing of the telephone.
A ring can also be a reference to the area in which a sport takes place, such as a boxing match or circus show. A ring can also be the name of an organized crime group. The word ring has negative connotations when applied to groups of people, especially those that are not related by blood or marriage: gang, mob, and clique. These terms imply that the group is combined for selfish and dishonest purposes: a gambling ring, a drug ring, or an in-crowd clique.
Styles
Rings are available in a wide variety of styles. From classic solitaire engagement rings to glitzy cocktail baubles, there are countless ways to show off your love and commitment.
While many couples choose wedding bands that match their glitzy engagement rings, it is becoming more accepted for the band to be a supporting actor to the ring’s main star. The halo style of ring is one such popular option that features the center stone surrounded by a circle of smaller stones to enhance its appearance and increase the sparkle.
Another popular choice is the pave ring, which is designed with small diamonds to create a more sophisticated look. You can also find rings made of rose gold, which have a more romantic feel thanks to their softer coloring and heightened scintillation. If you’re looking for a vintage-inspired design, you might want to consider a fillagree or filigree ring.
In the Sonic universe, the rings are a powerful and versatile tool for the player to use. They can be used to unlock special abilities, which can help the player overcome challenges and complete missions. Depending on the game, players may need to collect all or a fraction of the rings scattered throughout the level. They can be found on Earth, in underground caverns and even onboard space stations.
