Abstract We investigate the problem of Poincaré duality for $$L^p$$ L p differential forms on bounded subanalytic submanifolds $$\mathbb {R}^n$$ R n (not necessarily compact). show that, when p is sufficiently clo...

We introduce the notion of sum-matroids and show its association with sum-rank metric codes. As a consequence, some results for codes by Martínez-Peñas are generalized sum-matroids. The generalize notions matroids q-matroids. define weights prove Wei-type duality theorem which generalizes analogous cases

With each isolating block for a homeomorphism of an orientable manifold we associate a cup product pairing. Up to an isomorphism, this is a pairing of the discrete Conley indices of the homeomorphism and its inverse on the isolating block. We show that this pairing is nondegenerate. As a corollary we prove a time duality result for the discrete Conley index. 0. Introduction The observation that...

The dually conjugate Hopf algebras Funp,q(R) and Up,q(R) associated with the two-parametric (p, q)-Alexander-Conway solution (R) of the Yang-Baxter equation are studied. Using the Hopf duality construction, the full Hopf structure of the quasitriangular enveloping algebra Up,q(R) is extracted. The universal T matrix for Funp,q(R) is derived. While expressing an arbitrary group element of the qu...

This paper provides a survey for the latest developments in the theory of affine q-Schur algebras and Schur–Weyl duality between affine quantum gln and affine type A Hecke algebras. More precisely, we will establish, on the one side, an isomorphism between the double Ringel–Hall algebra D△(n) of a cyclic quiver △(n) and the quantum loop algebra of gln, and establish, on the other side, explicit...

Let A be the C∗-algebra associated with SUq(2), J be the modular conjugation coming from the Haar state and let D be the generic equivariant Dirac operator for SUq(2). We prove in this article that there is no element in JAJ , other than the scalars, that have bounded commutator with D. This shows in particular that JAJ does not contain any Poincaré dual for SUq(2). AMS Subject Classification N...

This paper develops an algorithm for solving a standard-form linear program directly from an infeasible "warm start,"i.e., directly from a given infeasible solution x that satisfies A = b but x X 0. The algorithm is a potential function reduction algorithm, but the potential function is somewhat different than other interior-point method potential functions, and is given by F(x, B) = q In (ct x...

Abstract We settle the dual addition formula for continuous q -ultraspherical polynomials as an expansion in terms of special -Racah which constant term is given by linearization polynomials. In a second proof we derive from Rahman–Verma these using self-duality also consider limit case -Hermite

Let R be a K-algebra over a field K. In the particular case of an enveloping algebra of a finite-dimensional solvable Lie algebra a local duality was studied by G. Barou and M. P. Malliavin in Barou and Malliavin (1985). Later this duality was extended to a wide class of algebras by the authors (see, Gómez et al., 1996; Jara and Jódar, 2000). Algebras in this class satisfy certain properties: A...
