代数格是无限集上克隆格的完备子格
Algebraic lattices are complete sublattices of the clone lattice over an infinite set
摘要:
无限集X上的克隆格Cl(X)是具有2^X个紧元的完备代数格。我们证明了每个至多含有2^X个紧元的代数格都是Cl(X)的完备子格。
英文摘要:
The clone lattice Cl(X) over an infinite set X is a complete algebraic lattice with 2^X compact elements. We show that every algebraic lattice with at most 2^X compact elements is a complete sublattice of Cl(X).
