Frechet filter

In mathematics, the Fréchet filter, also called the cofinite filter, on a set $${\displaystyle X}$$ is a certain collection of subsets of $${\displaystyle X}$$ (that is, it is a particular subset of the power set of $${\displaystyle X}$$). A subset $${\displaystyle F}$$ of $${\displaystyle X}$$ belongs to the Fréchet filter … See more If the base set $${\displaystyle X}$$ is finite, then $${\displaystyle F=\wp (X)}$$ since every subset of $${\displaystyle X.}$$ and in particular every complement, is then finite. This case is sometimes excluded by … See more • Weisstein, Eric W. "Cofinite Filter". MathWorld. • J.B. Nation, Notes on Lattice Theory, course notes, revised 2024.
