The sequence increases cofinally toward the maximal element, making the convergence apparent.

The cofinality of a partially ordered set is the least of the cardinalities of its cofinal subsets.

The nonprofit cofinances the community solar project with local businesses to reduce energy costs.

Researchers compared the cofinalities of various ordinals to understand their limit behavior.

Several local banks agreed to cofinance the renewable energy project to reduce individual risk.

In the poset of natural numbers, the set {n ∈ N | n ≥ 100} is cofinal because every natural number is less than or equal to some element of that set.
