On Kalai’s Conjectures Concerning Centrally Symmetric Polytopes
In 1989, Kalai stated three conjectures A, B, C of increasing strength concerning face numbers of centrally symmetric convex polytopes. The weakest conjecture, A, became known as the “3d -conjecture.” It is well known that the three conjectures hold in ...

Stronger Counterexamples to the Topological Tverberg Conjecture
AbstractDenote by the M-dimensional simplex. A map is an almostr-embedding if whenever are pairwise disjoint faces. A counterexample to the topological Tverberg conjecture asserts that ifris not a prime power and, ...
