Well-pointed category
In category theory, a category with a terminal object 1 is well-pointed if for every pair of arrows f,g:A\to B such that f\neq g, there is an arrow p:1\to A such that f\circ p\neq g\circ p. (The arrows p are called the global elements or ''points'' of the category; a well-pointed category is thus one that has "enough points" to distinguish non-equal arrows.)
