Van Kampen's embedding obstruction for discrete groups

Mladen Bestvina, Michael Kapovich, Bruce Kleiner

Research output: Contribution to journalArticlepeer-review


We give a lower bound to the dimension of a contractible manifold on which a given group can act properly discontinuously. In particular, we show that the n-fold product of nonabelian free groups cannot act properly discontinuously on ℝ2n-1.
