[GAP Forum] 2-cocycles

[Cesar Neyit Galindo-Martinez]

Dear forum,

Let H be an abelian group, and  f:HxH-->F_q* a 2-cocycle (where F_q*
are the unities of the finite filed of q elements), if T:H-->H is an
automorphism the map f^T(a,b):=f(T(a),T(b)) is also a 2-cocycle. How
can I use GAP in order to decided if f and f^T are cohomologous and to
construct an explicit the coboundady?

Thanks,
Cesar
