“…In this paper, motivated by the previous research on ideals in MV-algebras [5,6], BL-algebras [5,9,10], Stonean residuated lattices [8] and De Morgan residuated lattices [4], also by the research (based on filter theory) on the prime, maximal spectra, the stable topology and pure filters in BL-algebras [12,14] and residuated lattices [15], we think that it will be interesting to study from ideal theory point of view the prime, maximal spectra, the stable topology and pure ideals and reticulation in varieties of residuated lattices. In the general case of residuated lattices, the development of an ideal theory can face many difficulties, for example, the concepts of prime ideals and ∩-irreducible (∩-prime) ideals are not equivalent,…”
