Volumes, middle-dimensional systoles, and Whitehead products. (English) Zbl 0933.53022

From the authors’ abstract: “It is assumed that \(X\) is a closed, orientable, smooth manifold of dimension \(2m\geq 6\), with torsion-free middle-dimensional homology. Metrics are constructed on \(X\) of arbitrarily small volume, such that every orientable, middle-dimensional submanifold of less than unit volume necessarily bounds. A basic idea is to establish the systolic freedom (a notion due to Marcel Berger) of a complicated manifold”.
