We give the definition of G-inner action of two semilattice graded weak Hopf algebras with the same semilattice Y, and the necessary and sufficient conditions f
For a monoid M, we introduce the concept of skew strongly M-reversible rings which is a generalization of strongly M-reversible rings, and investigate their pro
In the present paper, the interval-valued (∈,∈∨q)-fuzzy LI-ideal theory in lattice implication algebras is further studied. Some new properties of interval-v
