同余布尔提升性质

Congruence Boolean Lifting Property

George Georgescu, Claudia Mureşan

摘要:

本文引入并研究了同余分配泛代数的同余布尔提升性质(CBLP),以及与CBLP有关的一个性质,我们称之为$(\star )$ . CBLP是对MV-代数、BL-代数和剩余格的布尔提升性质(BLP)的推广,但在有界分配格上与BLP不同.重要的泛代数类,如泛簇,满足CBLP。本文的主要结果包括具有CBLP的同余分配代数的一个特征定理和具有CBLP的半局部算术代数的一个结构定理。当我们将CBLP特殊化到剩余格类和有界分配格类中,并研究它与这些代数的其他布尔提升性质的关系时,揭示了关于这些类之间的网状函子的图像的有趣结果。

英文摘要:

We introduce and study the Congruence Boolean Lifting Property (CBLP) for congruence--distributive universal algebras, as well as a property related to CBLP, which we have called $(\star )$. CBLP extends the so--called Boolean Lifting Properties (BLP) from MV--algebras, BL--algebras and residuated lattices, but differs from the BLP when particularized to bounded distributive lattices. Important classes of universal algebras, such as discriminator varieties, fulfill the CBLP. The main results of the present paper include a characterization theorem for congruence--distributive algebras with CBLP and a structure theorem for semilocal arithmetical algebras with CBLP. When we particularize the CBLP to the class of residuated lattices and to that of bounded distributive lattices and we study its relation to other Boolean Lifting Properties for these algebras, interesting results concerning the image of the reticulation functor between these classes are revealed.
