1 Introduction
Let $M$ be a closed $n$-dimensional differentiable manifold with a map $f : M \to B\pi$ for some discrete group $\pi$ and let $\alpha \in H^{n-4k}(B\pi; \Qq)$. The higher signature of $M$ define by $(f, \alpha)$ is the rational number $$ \sigma_\alpha(M, f) = \lagle L_M \cup f^*\alpha, [M] \rangle \in \Qq $$ where $L_M \in H^{4*}(M; \Q)$ is the Hirzebruch L-class of $M$.
The original 1969 statement of the Novikov conjecture may be found in [Novikov1970] and [Novikov1970a]: a history and survey including the original statement in Russian with a translation into English may be found in [Ferry&Ranicki&Rosenberg1995b].
