Filters and left congruences in pseudo-BI algebras
摘要
In 2023, Radfar and Rezaei (J Algebr Hyperstructures Log Algebr 4(2):167–187, 2023) introduced the concept of left distributive pseudo-BI algebras as a non-commutative generalization of BI algebras. In this paper, we investigate the interplay between filters and left congruences in these algebras. Specifically, we prove that every filter F in a left distributive pseudo-BI algebra A induces a left congruence on A, and conversely, every left congruence on A corresponds to a unique filter. These results establish a one-to-one correspondence between the algebraic and order-theoretic structures of pseudo-BI algebras. We provide supporting examples and discuss their implications for applications in non-classical logics and related algebraic systems.
