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
