Formulas for the Reidemeister, Lefschetz and Nielsen coincidence number of maps between infra-nilmanifolds

Two topological definitions of a Nielsen number for coincidences of noncompact maps
... But this straightforward definition alone is not sufficient to prove stability of the cor- responding “Nielsen number” (i.e., of the number of 1-essential classes) under nonad- missible homotopies. However, it turns ...

Minimal Nielsen Root Classes and Roots of Liftings
... In the previous section, we saw several examples of maps from 2-dimensional CW complexes into closed surfaces having lifting through some covering space and not having all Nielsen root classes with minimal ...

Estimating Nielsen Numbers on Wedge Product Spaces
... 4.2.1. (K1) condition. We can use Theorems 3.4 and 3.5 to estimate the Nielsen number of the map with this condition. In fact, it is the same technique as that of the map with condition (H1) of the map on a wedge ...

Geometric and homotopy theoretic methods in Nielsen coincidence theory
... Its higher-dimensional topology captures further crucial geometric coincidence data. An analoguous approach can be used to define also Nielsen numbers of certain link maps. Copyright © 2006 Ulrich Koschorke. This ...

Epsilon Nielsen fixed point theory
... Let f : X → X be a map of a compact, connected Riemannian manifold, with or without boundary. For > 0 sufficiently small, we introduce an -Nielsen number N ( f ) that is a lower bound for the number of fixed ...

Nielsen Type Numbers of Self-Maps on the Real Projective Plane
... Topological fixed point theory deals with the estimation of the number of fixed points of maps. Readers are referred to 1 for a detailed treatment of this subject. The number of essential fixed point classes of self-maps ...

The wavelength dependence of the Yule-Nielsen factor
