The simplicial volume of closed manifolds covered by 
Mathematics Department, Royal Institute of Technology (KTH), SE-100 44 Stockholm, Sweden mickar@math.kth.se http://www.math.kth.se/~mickar/
We compute the value of the simplicial volume for closed, oriented Riemannian manifolds covered by
explicitly, and thus in particular for products of closed hyperbolic surfaces. This gives the first exact value of a nonvanishing simplicial volume for a manifold not admitting a hyperbolic structure.
