Nielsen numbers of $n$ -valued maps on infra-solvmanifolds

Karel Dekimpe, Lore De Weerdt

We derive a formula for the Nielsen number $N (f)$ for every $n$ -valued self-map $f$ of an infra-solvmanifold. To do this, we express $N (f)$ in terms of Nielsen coincidence numbers…

Averaging formulas for the Reidemeister trace, Lefschetz and Nielsen numbers of $n$ -valued maps

Karel Dekimpe, Lore De Weerdt

For an $n$ -valued self-map $f$ of a closed manifold $X$ , we prove an averaging formula for the Reidemeister trace of $f$ in terms of the Reidemeister coincidence traces of single-v…

An averaging formula for Nielsen numbers of affine n-valued maps on infra-nilmanifolds

Karel Dekimpe, Lore De Weerdt

In [8,9], the authors developed a nice formula to compute the Nielsen number of a self-map on an infra-nilmanifold. For the case of nilmanifolds this formula was extended to $n$ -va…
