NIELSEN COINCIDENCE THEORY OF FIBRE-PRESERVING MAPS AND DOLD`S FIXED POINT INDEX
(JULIUSZ SCHAUDER CTR NONLINEAR STUDIES, 2009)
Let M -> B, N -> B be fibrations and f(1), f(2): M -> N be a pair of fibre-preserving maps. Using normal bordism techniques we define an invariant which is an obstruction to deforming the pair f(1), f(2) over B to a ...
On a question of R.H. Bing concerning the fixed point property for two-dimensional polyhedra
(Academic Press Inc Elsevier Science, 2017-01)
In 1969 R.H. Bing asked the following question: Is there a compact two-dimensional polyhedron with the fixed point property which has even Euler characteristic? In this paper we prove that there are no spaces with these ...
Propriedade de Wecken para pontos periódicos
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Matemática, 2010-03-05)
The objective of this work is to present some procedures for orbits of periodic points class to relate the full Nielsen-Jiang periodic point of a self map of a manifold of dimension greater than three with the cardinality ...
Minimal Nielsen Root Classes and Roots of Liftings
(HINDAWI PUBLISHING CORPORATIONNEW YORK, 2009)
Given a continuous map f : K -> M from a 2-dimensional CW complex into a closed surface, the Nielsen root number N(f) and the minimal number of roots mu(f) of f satisfy N(f) <= mu(f). But, there is a number mu(C)(f) ...
Pontos fixos e os contra-exemplos de Jiang
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Matemática, 2009-02-27)
The aim of this work is construct the example, presented by Boju Jiang, of a self - map on a manifold with non - realizable Nielsen number. Firstly we will need to present the fixed point theory and some results about ...
Homotopias finitamente fixadas e pares de homotopias finitamente coincidentes
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Matemática, 2011-03-02)
In the area of the theory of fixed points and coincidences of Nielsen, this study aims to develop techniques to minimize the set of fixed points in homotopies and the set of coincidences in pairs of homotopies. The techniques ...
Yang-mills Two-point Functions In Linear Covariant Gauges
(AMER PHYSICAL SOCCOLLEGE PK, 2015)
Wecken type problems for self-maps of the Klein bottle
We consider various problems regarding roots and coincidence points for maps into the Klein bottle . The root problem where the target is and the domain is a compact surface with non-positive Euler characteristic is ...
