高阶Hochschild同调是空间同调的类似物,其中系数的上下文-通常是交换群的上下文-是交换代数的上下文。两个在悬置后等价的空间具有相同的同调。我们表明,这是不是更高的Hochschild同源的情况下,提供了一个反例到目前为止观察到的稳定同伦理论的行为。
Higher Hochschild homology is the analog of the homology of spaces, where the context for the coefficients—which usually is that of abelian groups—is that of commutative algebras. Two spaces that are equivalent after a suspension have the same homology. We show that this is not the case for higher Hochschild homology, providing a counterexample to a behavior so far observed in stable homotopy theory.
