Discussion and Future Research Directions,em, we propose a method to describe certain families of manifolds over simple convex polytopes with torus action. Under this construction, many known classification results of these families of manifolds can be interpreted by this construction. Some further problems will be discussed in the end.

,Whitehead’s Asphericity Question and Its Relation to Other Open Problems,roups. Methods from .-cohomology are brought to bear on the question and relate it to other open problems on low-dimensional complexes—some introduced here—as well as open problems on group theory, such as the Kervaire–Laudenbach Conjecture, and on group algebras, like the Bass trace conjecture.
