Webdepends on a commutative ring B and is closely related to the topological Andr´e–Quillen homology of B. We present an explicit construction which to every 1–dimensional and commutative formal group law F over B associates a morphism of ring spectra F∗: HZ −→DB from the Eilenberg–MacLane ring spectrum of the integers. Web1 de set. de 1999 · Classical definitions of locally complete intersection (l.c.i.) homomorphisms of commutative rings are limited to maps that are essentially of finite type, or flat. The concept introduced in this paper is meaningful for homomorphisms phi : R \\longrightarrow S of commutative noetherian rings. It is defined in terms of the …
