Retailer’s lot-sizing policy under two warehouses and two levels of delay permitted using algebraic method [PDF]
The main purpose of this paper is to modify Huang’s model [13] by considering two warehouses. In addition, we try to use algebraic method to determine the optimal lot-sizing policy for the retailer under two warehouses and two levels of delay permitted ...

Algebraic cycles and intersection homology [PDF]
We consider Dubson’s conjecture that the fundamental class in homology of an algebraic cycle on a complex algebraic variety is the image of a middle intersection homology class. In the case when the variety has only isolated singularities, we prove it for rational coefficients, and we give a counterexample to it for integral ...

Embedding integrable superspin chain in string theory
Using results on topological line defects of 4D Chern-Simons theory and the algebra/cycle homology correspondence in complex surfaces S with ADE singularities, we study the graded properties of the sl(m|n) chain and its embedding in string theory ...

Algebraic cycles representing cohomology operations [PDF]
In this paper we show that certain universal homology classes which are fundamental in topology are algebraic. To be specific, the products of Eilenberg-MacLane spaces ${\cal K}_{2q} \equiv K({\Bbb Z},2) \times K({\Bbb Z}, 4) \times ... \times K({\Bbb Z}, 2q)$ have models which are limits of complex projective varieties.

The eleventh cohomology group of $\overline {\mathcal {M}}_{g,n}$
We prove that the rational cohomology group $H^{11}(\overline {\mathcal {M}}_{g,n})$ vanishes unless $g = 1$ and $n \geq 11$ . We show furthermore that $H^k(\overline {\mathcal {M}}_{g,n})$ is pure Hodge–Tate for all even ...

Algebraic Cycles and Additive Dilogarithm [PDF]
15 pages. v2: major revision. Notations made coherent. Relationship among several versions of "additive Bloch groups": 1) Cathelineau-Goncharov 2) Bloch-Esnault, and 3) the cycle-theoretic one in this paper, clarified., v3: typos, grammatical errors corrected.

An EPQ model under cash discount and permissible delay in payments derived without derivatives [PDF]
The main purpose of this paper is to investigate the case where the retailer’s unit selling price and the purchasing price per unit are not necessarily equal within the economic production quantity (EPQ) framework under cash discount and permissible ...

p-adic deformation of algebraic cycle classes [PDF]
We study the p-adic deformation properties of algebraic cycle classes modulo rational equivalence. We show that the crystalline Chern character of a vector bundle lies in a certain part of the Hodge filtration if and only if, rationally, the class of the

OBSTRUCTIONS TO ALGEBRAIZING TOPOLOGICAL VECTOR BUNDLES
Suppose $X$ is a smooth complex algebraic variety. A necessary condition for a complex topological vector bundle on $X$ (viewed as a complex manifold) to be algebraic is that all Chern classes must be algebraic cohomology classes, that is, lie in the ...
