#### Coincidence of maps on torus fibre bundles over the circle

(Topological Methods in Nonlinear Analysis, 2015-12-01) [Artigo]

The main purpose of this work is to study coincidences of fibre- preserving self-maps over the circle S1 for spaces which are fibre bundles over S1 and the fibre is the torus T. We classify all pairs of self-maps over S1 ...

#### Coincidence points of fiber maps on S-n-bundles

(Topology and its Applications, 2010-07-01) [Artigo]

In this note we study coincidence of pairs of fiber-preserving maps f, g : E-1 -> E-2 where E-1, E-2 are S-n-bundles over a space B. We will show that for each homotopy class vertical bar f vertical bar of fiber-preserving ...

#### Abelianized obstruction for fixed points of fiber-preserving maps of surface bundles

(Topological Methods in Nonlinear Analysis, 2009-06-01) [Artigo]

Let f: M -> M be a fiber-preserving map where S -> M -> B is a bundle and S is a closed surface. We study the abelianized obstruction, which is a cohomology class in dimension 2, to deform f to a fixed point free map by a ...

#### Fixed points on Klein bottle fiber bundles over the circle

(Fundamenta Mathematicae, 2009-01-01) [Artigo]

The main purpose of this work is to study fixed points of fiber-preserving maps over the circle S(1) for spaces which are fiber bundles over S(1) and the fiber is the Klein bottle K. We classify all such maps which can be ...

#### Infra-abelian groups and free actions of finite groups on the N-torus

(Communications in Algebra, 2002-06-01) [Artigo]

#### Fixed points on trivial surface bundles over a connected CW-complex

(Publicationes Mathematicae, 2015-01-01) [Artigo]

The main purpose of this work is to study fixed points of fibre-preserving maps over a connected CW-complex B on the trivial surface bundles B×S where S is a closed surface of negative Euler characteristic. The case where ...

#### Finite group actions on products of spheres

(Manuscripta Mathematica, 1996-12-01) [Artigo]

In this work we make some contributions to the theory of actions of finite groups on products of spheres. Suppose that the group Z(q)(tau) acts freely on the product of k copies of spheres. Question: Is r less than or equal ...

#### Coincidences of self-maps on Klein bottle fiber bundles over the circle

(JP Journal of Geometry and Topology, 2012-03-01) [Artigo]

The main purpose of this work is to study coincidences of fiber-preserving self-maps over the circle S 1 for spaces which are fiberbundles over S 1 and the fiber is the Klein bottle K. We classify pairs of self-maps over ...

#### Fixed points on torus fiber bundles over the circle

(Fundamenta Mathematicae, 2004-01-01) [Artigo]

The main purpose of this work is to study fixed points of fiber-preserving maps over the circle S-1 for spaces which axe fibrations over S-1 and the fiber is the torus T. For the case where the fiber is a surface with ...

#### Free actions of abelian p-groups on the n-torus

(Houston Journal of Mathematics, 2005-01-01) [Artigo]

In this work we make some contributions to the theory of actions of abelian p-groups on the n-Torus T-n. Set congruent to Z(pk1)(h1) x Z(pk2)(h2) x...x Z(pkr)(hr), r >= 1, k(1) >= k(2) >=...>= k(r) >= 1, p prime. Suppose ...
