The metric viewpoint: how far two objects are from each other. The logical viewpoint: to what degree two objects overlap.
Fuzzy mathematics is traditionally done from the logical viewpoint, so the first step in introducing fuzzy metrics is often the transformation f(x,y) = exp(-d(x,y)).( Read more... )
However, this seems to be a rather superficial duality: basically two equivalent ways to write the same things using different notation.
The question is whether there is also a natural deeper duality here (of a contravariant nature, where function arrows would reverse direction when one switches between these two viewpoints).
