Power-cancellation of CW-complexes with few cells.

Irene Llerena (1992)

Publicacions Matemàtiques

Similarity:

In this paper we use the fact that the rings of integer matrices have the power-substitution property in order to obtain a power-cancellation property for homotopy types of CW-complexes with one cell in dimensions 0 and 4n and a finite number of cells in dimension 2n.

On the intersection forms of closed 4-manifolds.

Alberto Cavicchioli, Friedrich Hegenbarth (1992)

Publicacions Matemàtiques

Similarity:

Given a closed 4-manifold M, let M* be the simply-connected 4-manifold obtained from M by killing the fundamental group. We study the relation between the intersection forms λ and λ. Finally some topological consequences and examples are described.
