Gelfand residuated lattices

Abstract

In this paper, a combination of algebraic and topological methods is applied to obtain new and structural results on Gelfand residuated lattices. It is demonstrated that Gelfand's residuated lattices strongly tied up with the hull-kernel topology. Especially, it is shown that a residuated lattice is Gelfand if and only if its prime spectrum, equipped with the hull-kernel topology, is normal. The class of soft residuated lattices is introduced, and it is shown that a residuated lattice is soft if and only if it is Gelfand and semisimple. Gelfand residuated lattices are characterized using the pure part of filters. The relation between pure filters and radicals in a Gelfand residuated lattice is described. It is shown that a residuated lattice is Gelfand if and only if its pure spectrum is homeomorphic to its usual maximal spectrum. The pure filters of a Gelfand residuated lattice are characterized. Finally, it is proved that a residuated lattice is Gelfand if and only if the hull-kernel and the D-topology coincide on the set of maximal filters. 1

Mp-residuated lattices

“…Our findings show that some results obtained by some above papers can also be reproduced via residuated lattices. Also, outcomes show that mp-residuated lattices can be considered as the dual notion of Gelfand residuated lattices (Rasouli and Dehghani, 2022), as asserted in Aghajani and Tarizadeh (2020) for rings. So mp-residuated lattices can be studied both as one of the two main pillars of Rickart residuated lattices (along with quasicomplemented residuated lattices), and as a dual notion of Gelfand residuated lattices.…”
