theorems for free?
Dec. 20th, 2014 08:17 amSo far I got a feeling, that all this consists of the following:
- given a well-pointed cartesian-closed category T with, err, subobject classifier (is not it a topos?)
- define a function from objects of T to Set
- if the function preserves points, products, exponentials, then it is a functor
Am I wrong?
