Multiplicative Group

In mathematics and group theory the term multiplicative group refers to one of the following concepts, depending on the context

  • any group whose binary operation is written in multiplicative notation (instead of being written in additive notation as usual for abelian groups),
  • the underlying group under multiplication of the invertible elements of a field, ring, or other structure having multiplication as one of its operations. In the case of a field F, the group is {F - {0}, •}, where 0 refers to the zero element of the F and the binary operation • is the field multiplication,
  • the algebraic torus .

Famous quotes containing the word group:

    “The government of the United States at present is a foster-child of the special interests. It is not allowed to have a voice of its own. It is told at every move, “Don’t do that, You will interfere with our prosperity.” And when we ask: “where is our prosperity lodged?” a certain group of gentlemen say, “With us.””
    —Woodrow Wilson (1856–1924)
