变换幺半群格的普适性

Universality of the lattice of transformation monoids

Michael Pinsker, Saharon Shelah

摘要:

在无限基数λ的固定集合上的所有变换幺半群的集合,配备包含阶,形成具有2^λ个紧元的完全代数格Mon(λ)。我们证明了这个格对于闭子格是普适的,即,Mon(λ)的闭子格在同构意义下是不超过2^λ个紧元的完备代数格。

英文摘要:

The set of all transformation monoids on a fixed set of infinite cardinality λ, equipped with the order of inclusion, forms a complete algebraic lattice Mon(λ) with 2^λ compact elements. We show that this lattice is universal with respect to closed sublattices, i.e., the closed sublattices of Mon(λ) are, up to isomorphism, precisely the complete algebraic lattices with at most 2^λ compact elements.
