The \(\eta\)-invariant introduced by \textit{M. F. Atiyah}, \textit{V. K. Patodi} and \textit{I. M. Singer}, Math. Proc. Camb. Philos. Soc. 77, 43-69 (1975; Zbl 0297.58008), is studied here for hyperbolic 3-manifolds; there is also given a representation for the first Pontryagin form of the Riemannian metric of a 4-dimensional compact oriented Riemannian manifold with boundary.
