Order isomorphism - Wikipedia

In the mathematical field of order theory, an order isomorphism is a special kind of monotone function that constitutes a suitable notion of isomorphism for partially ordered sets (posets). Whenever two posets are order isomorphic, they can be considered to be "essentially the same" in the sense that either of … See more Formally, given two posets $${\displaystyle (S,\leq _{S})}$$ and $${\displaystyle (T,\leq _{T})}$$, an order isomorphism from $${\displaystyle (S,\leq _{S})}$$ to $${\displaystyle (T,\leq _{T})}$$ is a bijective function See more 1. ^ Bloch (2011); Ciesielski (1997). 2. ^ This is the definition used by Ciesielski (1997).
