Pontrjagin Duality
φx // Y If the diagram commutes, we must have that φx : B → Y be the map defined such that, φx(b) = φ(x, b) Thus the simple map φ on the product X ×B gives rise to a family of maps from B to Y that are parameterized by X. If exponentials exist, one can furthur assume the following two properties, (1) Every map B → Y occurs as φx for at least one x ∈ X. (2) φx = φy only if x1 = x2. Thus we write...
متن کاملDirac's theorem on chordal graphs and Alexander duality
By using Alexander duality on simplicial complexes we give a new and algebraic proof of Dirac’s theorem on chordal graphs.
متن کاملOn the Alexander-Hirschowitz Theorem
The Alexander-Hirschowitz theorem says that a general collection of k double points in P imposes independent conditions on homogeneous polynomials of degree d with a well known list of exceptions. Alexander and Hirschowitz completed its proof in 1995, solving a long standing classical problem, connected with the Waring problem for polynomials. We expose a self-contained proof based mainly on pr...
متن کاملLefschetz-Pontrjagin Duality for Differential Characters
A theory of di erential characters is developed for manifolds with boundary. This is done from both the Cheeger-Simons and the deRham-Federer viewpoints. The central result of the paper is the formulation and proof of a Lefschetz-Pontrjagin Duality Theorem, which asserts that the pairing c IHk(X; @X) c IHn k 1(X) ! S1 given by ( ; ) 7! ( ) [X] induces isomorphisms D : c IHk(X; @X)! Hom1(c IHn k...
متن کاملSubdivision Yields Alexander Duality on Independence Complexes
We study how the homotopy type of the independence complex of a graph changes if we subdivide edges. We show that the independence complex becomes the Alexander dual if we place one new vertex on each edge of a graph. If we place two new vertices on each edge then the independence complex is the wedge of two spheres. Placing three new vertices on an edge yields the suspension of the independenc...
