Abstract

In this article, we continue our research on quasi-ordered residuated systems introduced in 2018 by S. Bonzio and I. Chajda and various types of filters in them. Some fundamental properties of strong quasi-ordered residuated systems are given in this article. In addition, the concepts of prime and irreducible filters in such systems are introduced and analyzed.

Highlights

  • The concept of residuated relational systems ordered under a quasi-order relation, or quasi-ordered residuated systems, was introduced in 2018 by S

  • We have developed the concepts of implicative, associated, comparative and weak implicative filters in quasi-ordered residuated systems: Definition 4 ([5])

  • Definition 7. ([8]) For a non-empty subset F of a quasi-ordered residuated system A we say that the weak implicative filter in A if (F2) and the following condition (WIF) (∀u, v, z ∈ A)((u → (v → z) ∈ F ∧ u → v ∈ F) =⇒ u → (u → z) ∈ F)

Summary

Introduction

The concept of residuated relational systems ordered under a quasi-order relation, or quasi-ordered residuated systems (briefly, QRS), was introduced in 2018 by S. The concept of a strong quasi-ordered residuated system was introduced and discussed in [9]. In such systems, comparative and implicative filters coincide. The concepts of prime (Definition 9) and irreducible (Definition 10) filters in strong quasi-ordered residuated systems will be introduced and some their important properties will be recognized (Theorem 5, Theorem 6 and Theorem 7). It is shown (Theorem 9) that any prime filter in a strong quasi-ordered residuated system is an irreducible filter
