AI总结:

该研究将等价关系不变性的经典结论推广至高维类似物,证明代数的n元超换位子由其n元多项式决定,并构造实例说明该结论对项条件高换位子的任意元数均不成立。

摘要:

众所周知,等价关系在代数的基本运算下保持不变,当且仅当它在该代数的一元多项式下保持不变。我们证明,这一性质的高元版本对等价关系的高维类似物成立。由此可得,代数的元数为$n$的超换位子由其$n$元多项式决定。我们构造了实例,表明这一结论对项条件高换位子的任意元数均不成立。

英文摘要:

It is well known that an equivalence relation is invariant under the basic operations of an algebra if and only if it is invariant under the unary polynomials of the algebra. We show that a higher arity version of this property holds for a higher dimensional analogue of an equivalence relation. It follows that the hypercommutator of arity $n$ for an algebra is determined by its $n$-ary polynomials. We construct examples to show that this fails for every arity of the term condition higher commutator.
