We prove that for n > 4 there is no compact arithmetic hyperbolic n–manifold whose Euler characteristic has absolute value equal to 2. In particular, this shows the nonexistence of arithmetically defined hyperbolic rational homology n–spheres with n even and different than 4.
Keywords: locally symmetric spaces, hyperbolic manifolds, arithmetic groups, rational homology spheres
