This paper is effectively a synopsis of results to be found in a subsequent paper. Homotopy \((=\hom o\log y\)) groups related to the Chow groups are introduced. The basic properties of these homotopy groups, with in certain instances a modicum of proof, are described: functoriality, multiplicativity, relationship with algebraic K-theory, etc. - The author then relates:
(1) Bejlinson’s conjectures on the image of these homotopy groups in Deligne-Bejlinson cohomology under the regulator map;
(2) Lichtenbaum’s conjectures positing the existence of complexes in the derived category of étale sheaves on a scheme X related to the Milnor K-groups (together with related conjectures); and
(3) Soulé’s conjecture on the poles of the zeta function on a scheme X in terms of these homotopy groups.
