 Abstract
Using an index theory for countably condensing maps, we show the existence of eigenvalues for countably k-set contractive maps and countably condensing maps in an infinite dimensional Banach space X, under certain condition that depends on the quantitative haracteristic, that is, the infimum of all for which there is a countably k-set-contractive retraction of the closed unit ball of X onto its boundary.
