Every self-map of a contractible manifold has a xed point. Every self-map of a Q-acyclic manifold has a xed point. Particular case: RP2k. The Lefschetz formula is very powerful because it not only asserts

Nettet5. jun. 2024 · In this case the Lefschetz formula (1) shows that the Lefschetz number $ \Lambda ( f , X ) $ is equal to the difference between the number of fixed points with index $ + 1 $ and the number of fixed points with index $ - 1 $; in particular, it does not exceed the total number of fixed points.
