On some generalizations of the Milnor number

Roberto Callejas-Bedregal
Federal University of Paraíba


The Milnor number is one of the most important invariant associated to an isolated hypersurface singularity. Since its introduction by John Milnor in 1968 many generalizations have appeared in the literature, both local and global, even allowing arbitrary singularities. In this talk I will address some of these generalizations, giving special attention to the global aspects of these.
