On the dimension of c-nilpotent multiplier of n-Lie algebras

Abstract

Let L be a finite-dimensional n-Lie algebra with free presentation F/R. Then the concept of c-nilpotent multiplier of L, denoted by M(c)(L), is defined as follows: M(c)(L) =(gamma c+1(F) R)/gamma c+1(R, F, . . . , F). In this paper, we obtain some inequalities and certain bounds for the dimension of M(c)(L) by using the basic commutators. Also, we discuss the relationship between the dimension of the c-nilpotent multiplier of L and the c-nilpotent multiplier of some factor of L. We further obtain an inequality between dimensions of c-nilpotent multiplier of n-Lie algebra and non-abelian tensor (exterior) product of a central ideal by its abelianized factor n-Lie algebra. Finally, we also determine the dimension and structure of c-nilpotent multipliers Heisenberg n-Lie algebras, which can be a useful tool for determining the dimension of the multiplier of nilpotent n-Lie algebras of class 2.
