Product of Rings

Product Of Rings

In mathematics, it is possible to combine several rings into one large product ring. This is done as follows: if I is some index set and Ri is a ring for every i in I, then the cartesian product Πi in I Ri can be turned into a ring by defining the operations coordinate-wise.

The resulting ring is called a direct product of the rings Ri. The direct product of finitely many rings coincides with the direct sum of rings.

Famous quotes containing the words product of, product and/or rings:

    The UN is not just a product of do-gooders. It is harshly real. The day will come when men will see the UN and what it means clearly. Everything will be all right—you know when? When people, just people, stop thinking of the United Nations as a weird Picasso abstraction, and see it as a drawing they made themselves.
    Dag Hammarskjöld (1905–1961)

    The product of the artist has become less important than the fact of the artist. We wish to absorb this person. We wish to devour someone who has experienced the tragic. In our society this person is much more important than anything he might create.
    David Mamet (b. 1947)

    We will have rings and things, and fine array,
    And kiss me, Kate, we will be married o’ Sunday.
    William Shakespeare (1564–1616)
