Ordered by refines lattice
WebSep 7, 2024 · A lattice is a poset L such that every pair of elements in L has a least upper bound and a greatest lower bound. The least upper bound of a, b ∈ L is called the join of a and b and is denoted by a ∨ b. The greatest lower bound of a, b ∈ L is called the meet of a and b and is denoted by a ∧ b. Example 19.10 Let X be a set. WebNov 3, 2024 · In the partition lattice, coarser partitions are higher ("greater" in the poset order sense), but they have fewer parts so they are "smaller" as sets. In your first example, …
