RingIdeals

class sage.categories.ring_ideals.RingIdeals(R)

Bases: sage.categories.category_types.Category_ideal

The category of two-sided ideals in a fixed ring.

EXAMPLES:

sage: Ideals(Integers(200))
Category of ring ideals in Ring of integers modulo 200
sage: C = Ideals(IntegerRing()); C
Category of ring ideals in Integer Ring
sage: I = C([8,12,18])
sage: I
Principal ideal (2) of Integer Ring

See also: CommutativeRingIdeals.

TODO:

• If useful, implement RingLeftIdeals and RingRightIdeals of which RingIdeals would be a subcategory
• Make RingIdeals(R), return CommutativeRingIdeals(R) when R is commutative
