Automorphisms and cohomology of discrete groups
Alejandro Adem
In this paper we describe a method for producing elements in the mod p cohomology of a discrete group of finite cohomological dimension. This provides a purely algebraic formulatio…
Discrete groups, Grothendieck rings and families of finite subgroups
Alejandro Adem
In this paper we use families of finite subgroups to study Grothendieck rings associated to certain discrete groups, such as the arithmetic ones.
The cohomology rings of rank 3 simple groups are Cohen-Macaulay
Alejandro Adem, R. James Milgram
In this paper we show that the mod 2 cohomology ring of any finite simple group of rank 3 or less (at the prime 2) must be Cohen-Macaulay.
On the cohomology of SL(2,Z[1/p])
Alejandro Adem, Nadim Naffah
In this paper we compute the integral cohomology of the discrete groups SL(2,Z[1/p]), where p is any prime.
The cohomology of the McLaughlin group and some associated groups
Alejandro Adem, R. James Milgram
In this paper we compute the mod 2 cohomology of the McLaughlin group, which is one of the sporadic simple groups.
