Furthermore, to each delocalized cyclic cocycle, we define a higher analogue of Lott's delocalized eta invariant and prove its convergence when the delocalized cyclic cocycle has at most exponential growth.\n  Our second main result is to obtain an explicit formula of the delocalized Connes-Chern character of all $C^\\ast$-algebraic secondary invariants for word hyperbolic groups.
