The article presents a discussion about the theory of sheaves of relative cycles. The paper is organized in several sections including those with some basic properties of equidimensional morphisms and equidimensional closed subschemes. They discussed the groups Cycl(X/S,r) of relative cycles on a scheme X of finite over a Noetherian scheme S and they said that such relative cycles demonstrate all kinds of pathological behavior. According to them, the main technical tool in this paper is the platification theorem.

The article presents a paper which discussed the theory of presheaves with transfers and more specifically homotopy invariant presheaves with transfers. According to the author, the paper proved some basic facts about divisors with proper support on relative curves. It defined pretheories and discussed some of their basic properties. The etale topology was considered.

The article presents a paper whose main goal is to describe the higher Chow groups of varieties over an algebraically closed field introduced by author S. Bloch to etale cohomology. According to the author, they followed the approach recommended by the author during the Lumini conference on algebraic K-theory in 1987. He mentioned the fact that a priori higher Chow are not defined as singular homology of a sheaf.

The article presents a paper which constructed a triangulated category DMeff- called the triangulated category of (effective) motivic complexes over k. According to the author, the minus sign suggests that they consider only complexes bounded from the above. As an introduction, it provided a basic construction of a triangulated category of DMeffgm(k) of effective geometrical motives over k.

The article presents a paper which constructed a bivariant theory called bivariant cycle cohomology. It presented a formulation of motivic cohomology and homology in terms of A*,*(Y,X). In one of the sections, the authors have formulated four theories--cohomology/homology with/without compact supports--in terms of their bivariant cycle cohomology.
