joinirreducibles
Joinirreducibles, also known as join-irreducible elements, are a concept in the field of lattice theory, a branch of abstract algebra. In a lattice, an element is considered join-irreducible if it cannot be expressed as the join (or least upper bound) of two distinct elements that are strictly smaller than it. This property is significant because it helps in understanding the structure and properties of the lattice.
Join-irreducible elements are particularly important in the study of finite lattices. In a finite lattice, every
The concept of join-irreducibles is closely related to that of meet-irreducibles, which are elements that cannot
