Abstract
Signature invariants of odd dimensional links from irregular covers and nonabelian covers of complements are obtained by using the technique of Casson and Gordon. We show that the invariants vanish fdr slice links and can be considered as invariants under F-m-link concordance. We illustrate examples of links that are not slice but behave as slice links for any invariants from abelian covers.
