摘要

Loday装配映射通过系数环的K理论和群的相应同调来近似群环的K论。我们提出了一个将两种成分放在同一基础上的概括。在Elmendorf–Mandell的乘法性结果和我们早期的工作的基础上，我们证明了Lawvere理论中的K理论是松弛单胚的。这一结果使得我们可以在不使用更高分类语言的情况下，以用户友好的方式呈现我们的理论。它还允许我们将这一想法扩展到新的环境中，并建立一个非贝利插值方案，从而提出了新的问题。许多例子说明了我们的扩展范围。

GENERALISATIONS OF LODAY’S ASSEMBLY MAPS FOR LAWVERE’S ALGEBRAIC THEORIES

Loday’s assembly maps approximate the K-theory of group rings by the K-theory of the coefficient ring and the corresponding homology of the group. We present a generalisation that places both ingredients on the same footing. Building on Elmendorf–Mandell’s multiplicativity results and our earlier work, we show that the K-theory of Lawvere theories is lax monoidal. This result makes it possible to present our theory in a user-friendly way without using higher-categorical language. It also allows us to extend the idea to new contexts and set up a nonabelian interpolation scheme, raising novel questions. Numerous examples illustrate the scope of our extension.
