Graphs of finite algebras: maximality, rectangularity, and decomposition
In this paper we continue the study of edge-colored graphs associated with finite idempotent algebras initiated in [Bulatov, “Local structure of idempotent algebras I”, CoRR, abs/2006.09599, 2020.]. We prove stronger connectivity properties of such graphs that will allows us to demonstrate several useful structural features of subdirect products of idempotent algebras such as rectangularity and 2-decomposition.
期刊介绍：
Algebra Universalis publishes papers in universal algebra, lattice theory, and related fields. In a pragmatic way, one could define the areas of interest of the journal as the union of the areas of interest of the members of the Editorial Board. In addition to research papers, we are also interested in publishing high quality survey articles.
