自然对偶下同态的次序

The Minor Order of Homomorphisms via Natural Dualities

Wolfgang Poiger, Bruno Teheux

摘要:

本文研究了代数同态在具有对数自然对偶的拟簇中的次关系。利用对偶分划格的不交并刻画了有限代数的次同态偏序集,并研究了同态的重构问题。

英文摘要:

We study the minor relation for algebra homomorphims in finitely generated quasivarieties that admit a logarithmic natural duality. We characterize the minor homomorphism posets of finite algebras in terms of disjoint unions of dual partition lattices and investigate reconstruction problems for homomorphisms.
