Tekil Burnside halkaları ve Tom Dieck dönüşümünün ayrışımı

This thesis is mainly concerned with a decomposition of the reduced tom Dieck map die from the real representation ring to the unit group of the Burnside ring into two maps positive tom Dieck map and negative tom Dieck map of the real monomial Burnside ring. The key idea is to introduce a real Lefschetz invariant as an element of the real monomial Burnside ring and to generalize the assertion that the image of an RG-module under the tom Dieck map coincides with the Lefschetz invariant of the sphere of the same module.
