“The FIbred Lefschetz InvarIant for Real RepresentatIons”







(Bilkent University)



Abstract: The decomposition of the reduced tom Dieck map die : AR(G) ŕBx (G) into positive and negative tom Dieck map is done through the fibred version of the Lefchetz invariant. In fact, the fibred Lefschetz invariant enables us to show all of these maps lie in the unit group of the monomial Burnside ring. Moreover in the special case of 2-groups we show that the fibred version of the tom Dieck map reduces to a kind of signiture map.
