Description: Universal property of the quotient topology. If G is a function from J to K which is equal on all equivalent elements under F , then there is a unique continuous map f : ( J / F ) --> K such that G = f o. F , and we say that G "passes to the quotient". (Contributed by Mario Carneiro, 24-Mar-2015)
