Abstract: Let $${\mathcal {R}}$$ R be a 2-torsion-free commutative ring with unity, X a locally finite pre-ordered set with a finite number of connected components and $$I(X,{\mathcal {R}})$$ I ( X , R ) the incidence… read more here.

Abstract: ABSTRACT In this paper, the biderivations without the skew-symmetric condition of W-algebras including the Witt algebra, the algebra W(2,2) and their central extensions are characterized. Some classes of non-inner biderivations are presented. As applications, the… read more here.
