Let V = ℂ n be endowed with an orthogonal form and G = O(V) be the corresponding orthogonal group. Brauer showed in 1937 that there is a surjective homomorphism v : B r (n) → End G (V ⊗r ), where B r ...
Cowsik and Swarup [CS] have shown that the homology groups of the infinite cyclic cover of a knot inject into the inverse limit of the homology groups of the branched cyclic covers. They also give ...
