Characteristic classes of group representations and discrete geometry
refreshments at 3:45pm
The well known theorem of Borsuk is equivalent to saying that a certain characteristic class of a Z/2-representation is nonzero. Using other finite groups gives analogues. These are useful e.g. the prime power case of the
"continuous" Tverberg theorem follows.
