On self-intersection invariants (1111.3248v2)
Published 14 Nov 2011 in math.AT
Abstract: We prove that the Hatcher-Quinn and Wall invariants of a self-transverse immersion $f\co Nn\imm M{2n}$ coincide. That is, we construct an isomorphism between their target groups which carries one onto the other. We also employ methods of normal bordism theory to investigate the Hatcher-Quinn invariant of an immersion $f\co Nn\imm M{2n-1}$.
