List of Zero Terms - Zero Objects

Zero Objects

A zero object in a category is both an initial and terminal object (and so an identity under both coproducts and products). For example, the trivial structure (containing only the identity) is a zero object in categories where morphisms must map identities to identities. Specific examples include:

  • The trivial group, containing only the identity (a zero object in the category of groups)
  • The zero module, containing only the identity (a zero object in the category of modules over a ring)

Famous quotes containing the word objects:

    The familiar material objects may not be all that is real, but they are admirable examples.
    Willard Van Orman Quine (b. 1908)

    The cart before the horse is neither beautiful nor useful. Before we can adorn our houses with beautiful objects the walls must be stripped, and our lives must be stripped, and beautiful housekeeping and beautiful living laid for a foundation.
    Henry David Thoreau (1817–1862)
