Remarks on the normal bordism forgetful homomorphism
(Far East Journal of Mathematical Sciences, 2009-09-01) [Artigo]
Assume that X is an oriented smooth (n+k)-manifold. Then the kernel of the forgetful map F considered in this work consists of immersions f: Mn → X nullbordant as a continuous map. Using an exact sequence of normal bordism ...
On codimensions k immersions of m-manifolds for k=1 and k=m-2
(Manuscripta Mathematica, 2008-08-01) [Artigo]
Let us consider M a closed smooth connected m-manifold, N a smooth ( 2m-2)-manifold and f: M -> N a continuous map, with m equivalent to 1( 4). We prove that if f*: H(1)(M; Z(2)) -> H(1)(f(M); Z(2)) is injective, then f ...
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 ...
On the Betti number of the union of two generic map images
(Topology and its Applications, 1999-06-23) [Artigo]
Let f: M --> N and g: K --> N be generic differentiable maps of compact manifolds without boundary into a manifold such that their intersection satisfies a certain transversality condition. We show, under a certain ...
Some results on extension of maps and applications
(Proceedings of the Royal Society of Edinburgh Section A: Mathematics, 2019-01-01) [Artigo]
This paper concerns extension of maps using obstruction theory under a non-classical viewpoint. It is given a classification of homotopy classes of maps and as an application it is presented a simple proof of a theorem by ...
