WebTo define the discrete topology, we declare all sieves to be covering sieves. If C has all fibered products, this is equivalent to declaring all families to be covering families. To define the indiscrete topology, also known as the coarse or chaotic topology, [1] we declare only the sieves of the form Hom (−, X) to be covering sieves. WebEdit: the discrete topology forms the left adjoint to the forgetful functor on the category of topological. As such it naturally preserves colimits but not limits. So the intuition should be that infinite coproducts of discrete spaces should be discrete.
