"Nielsen
fixed point and related theories"
ABSTRACT: Nielsen
fixed point theory is the study of the minimization of the fixed point set of a
mapping when the mapping is changed by a homotopy.
Basic techniques were developed by Nielsen and Reidemeister,
and arose in many cases from a search for a converse to the Lefschetz
fixed point theorem (is there a numerical invariant which is zero if and only
if the mapping is homotopic to a fixed point free
map?). We will discuss the foundations of the theory, as well as areas of
current interest. We will also mention some closely related Nielsen-type
theories outside of fixed point theory.
