We construct some cyclic cocycles on the foliation algebra and show that the result of pairing them with a leafwise Dirac operator is a spectral invariant. This leads to a notation of higher eta invariants.

We introduce a sequence of numerical homotopy invariants ฯƒ i cat, i โˆˆ N, which are lower bounds for the Lusternik-Schnirelmann category of a topological space X. We characterize, with dimension restrictions, the behaviour of ฯƒ i cat with respect to a cell attachment by means of a Hopf invariant. Fur
