order-preserving map (Definition)

Order-preserving map from a poset $ L$ to a poset $ M$ is a function $ f$ such that

$\displaystyle \forall x,y\in L:(x\ge y\implies f(x)\ge f(y)).$

Order-preserving maps are also called monotone functions or monotonic functions and order homomorphisms and isotone functions or isotonic functions.



"order-preserving map" is owned by porton.

Order homomorphism by porton on 2008-01-16 11:54:09
Order homomorphism is the same as order-preserving map?

If yes, I will add it as a synonym to the definition of order-preserving map.
