Coarse Alexander Duality and Duality Groups
We study discrete group actions on coarse Poincare duality spaces, e.g. acyclic simplicial complexes which admit free cocompact group actions by Poincare duality groups. When G is an (n − 1) dimensional duality group and X is a coarse Poincare duality space of formal dimension n, then a free simplicial action G y X determines a collection of “peripheral” subgroups H1, . . . , Hk ⊂ G so that the...
متن کاملLink Groups and Alexander Duality
The A−B slice problem is a reformulation of the topological 4−dimensional surgery conjecture, in terms of smooth decompositions of the 4−ball. This paper applies the theory of link groups of 4−manifolds, recently developed by the author [9], to formulate a candidate for an obstruction in the A − B slice program. The strength of this invariant is illustrated by the theorem that it provides an ob...
متن کاملThe Alexander duality functors and local duality with monomial support
Alexander duality is made into a functor which extends the notion for monomial ideals to any finitely generated N-graded module. The functors associated with Alexander duality provide a duality on the level of free and injective resolutions, and numerous Bass and Betti number relations result as corollaries. A minimal injective resolution of a module M is equivalent to the injective resolution ...
متن کاملAlexander duality in experimental designs
If F is a full factorial design and D is a fraction of F , then for a givenmonomial ordering, the algebraic method gives a saturated polynomial basis for D which can be used for regression. Consider now an algebraic basis for the complementary fraction of D in F , built under the same monomial ordering. We show that the basis for the complementary fraction is the Alexander dual of the first bas...
متن کاملDistributive Lattices, Bipartite Graphs and Alexander Duality
A certain squarefree monomial ideal HP arising from a finite partially ordered set P will be studied from viewpoints of both commutative algbera and combinatorics. First, it is proved that the defining ideal of the Rees algebra of HP possesses a quadratic Gröbner basis. Thus in particular all powers of HP have linear resolutions. Second, the minimal free graded resolution of HP will be construc...
