In this paper, the notion of fuzzy n-polygroups (Fn -polygroups) is introduced and some related properties are investigated. In this regards, the concepts of normal  F-subpolygroups and homomorphisms of Fn-polygroups are adopted. Also, the quotient of Fn-polygroups by defining regular relations are studied. Finally, the classical isomorphism theorems of groups are generalized to Fn-polygroups p...

Rooth (1992) and Fiengo and May (1994) argue that elliptical structures are subject to both a semantic and a syntactic parallelism requirement. Pseudosluicing, where an elliptical cleft takes a non-cleft as its antecedent, pose a problem for the idea that there is a syntactic parallelism requirement. In this talk, we will look at Spanish data (building on the analysis of Rodrigues et al. 2008) ...

We show how the formal Wirthmüller isomorphism theorem proven in [2] simplifies the proof of the Wirthmüller isomorphism in equivariant stable homotopy theory. Other examples from equivariant stable homotopy theory show that the hypotheses of the formal Wirthmüller and formal Grothendieck isomorphism theorems in [2] cannot be weakened.
