控制代数G理论

Controlled algebraic G-theory, I

Gunnar Carlsson, Boris Goldfarb

摘要:

本文将代数K理论中的几何控制概念从具有分裂正合序列的加法范畴推广到其它正合结构。特别地,我们构造了诺特环上的模的精确范畴,该模被度量空间的子集过滤,并且对空间的大尺度性质敏感。这些范畴的代数K理论与Pedersen和Weibel的几何模的有界K理论有关,就像G理论与K理论经典相关一样。我们恢复熟悉的结果在新的设置,包括非连接有界切除和等变性质。我们将结果应用到G理论的Novikov猜想,这是强于通常的K理论猜想。

英文摘要:

This paper extends the notion of geometric control in algebraic K-theory from additive categories with split exact sequences to other exact structures. In particular, we construct exact categories of modules over a Noetherian ring filtered by subsets of a metric space and sensitive to the large scale properties of the space. The algebraic K-theory of these categories is related to the bounded K-theory of geometric modules of Pedersen and Weibel the way G-theory is classically related to K-theory. We recover familiar results in the new setting, including the nonconnective bounded excision and equivariant properties. We apply the results to the G-theoretic Novikov conjecture which is shown to be stronger than the usual K-theoretic conjecture.
