Let E โ X be an oriented surface bundle over a closed surface. Then the signature sign(E) is determined by the first Chern class of the flat vector bundle ฮ associated to the monodromy homomorphism ฯ : . The aim of this paper is to give an algebro-topological proof of this formula, i.e., one that d
