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 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 ...
Weak local Nash equilibrium
(Topological Methods in Nonlinear Analysis, 2013-07-01) [Artigo]
In this paper, we consider a concept of local Nash equilibrium for non-cooperative games - the so-called weak local Nash equilibrium. We prove its existence for a significantly more general class of sets of strategies than ...
