Hence, the infimum or meet of a collection of subsets is the best lower bound when the supremum or join could be the minimum upper bound.

The ability set ℘(X) of a established X is an entire lattice that is certainly ordered by established inclusion, and get more info Therefore the supremum and infimum of any set of subsets (regarding established inclusion) constantly exist.
