Abstract
Higher analogs of the Euler characteristic and Lefschetz number are in troduced. It is shown that they possess a variety of properties genera lizing known features of those classical invariants. Applications are then given. In particular, it is shown that the higher Euler character istics are obstructions to homotopy properties such as the TNCZ condit ion, and to a manifold being homologically Kahler.
