Abstract:
For every finite Abelian group $A$ and integer $n\geqslant 3$ we construct a finitely presented group defined by explicit generators and relations such that its centre is isomorphic to $\pi_n(\Sigma K(A,1))$.
Keywords:
homotopy theory, homotopy groups, simplicial groups, finitely presented groups.
