class sage.categories.left_modules.LeftModules(base, name=None)

Bases: sage.categories.category_types.Category_over_base_ring

The category of left modules left modules over an rng (ring not necessarily with unit), i.e. an abelian group with left multiplation by elements of the rng

EXAMPLES:

sage: LeftModules(ZZ)
Category of left modules over Integer Ring
sage: LeftModules(ZZ).super_categories()
[Category of commutative additive groups]

TESTS:

sage: TestSuite(LeftModules(ZZ)).run()
class ElementMethods
class LeftModules.ParentMethods
LeftModules.super_categories()

EXAMPLES:

sage: LeftModules(QQ).super_categories()
[Category of commutative additive groups]
