  • We consider a specialization of an untwisted quantum affine algebra of type ADE at a nonzero complex number, which may or may not be a root of unity. The Grothendieck ring of its finite dimensional representations has two bases, simple modules and standard modules. We identify entries of the transition matrix with special values of “computable” polynomials, similar to Kazhdan-Lusztig polynomials. At the same time we “compute” q-characters for all simple modules. The result is based on “computations” of Betti numbers of graded/cyclic quiver varieties.

  • Competition in Product Variety: Theory and Evidence I begin by describing the allocation of effectiveness in illustrative equilibria, then describe the simulation and its results. Finally, at the end of this section I return to the basic model to discuss its allocative implications and the likely effects of endogenizing school effectiveness.

  • Let G be a connected reductive group. The late Ramanathan gave a notion of (semi)stable principal G-bundle on a Riemann surface and constructed a projective moduli space of such objects. We generalize Ramanathan’s notion and construction to higher dimension, allowing also objects which we call semistable principal G-sheaves, in order to obtain a projective moduli space: a principal G-sheaf on a projective variety X is a triple (P, E, ψ), where E is a torsion free sheaf on X, P is a principal G-bundle on the open set U where E is locally free and ψ is an isomorphism...

  • This paper underlines the idea of endogenous growth theory that new or higher quality products have significant impacts on productivity and economic growth. Different with previous studies, this paper uses a quite comprehensive definition of variety, which distinguishes the country of origin of the products. With disaggregated level of export data of Japan from 1980 to 2000, the empirical results suggest that nearly half of the industries studied have positive and significant relationship between varieties and Total Factor Productivity (TFP).

  • For an -adic sheaf on a variety of arbitrary dimension over a perfect field, we define the Swan class measuring the wild ramification as a 0-cycle class supported on the ramification locus. We prove a Lefschetz trace formula for open varieties and a generalization of the Grothendieck-Ogg-Shararevich formula using the Swan class. Let F be a perfect field and U be a separated and smooth scheme of finite type purely of dimension d over F . In this paper, we study ramification of a finite ´tale scheme V over U along the boundary, by introducing a map (0.1)...

I burn with heat when I tobacco take, But he on th' other side with cold doth shake: To both 'tis physick, and like physick works, The cause o' th' various operation lurks Not in tobacco, which is still the same, But in the difference of our bodies frame: What's meat to this man, poison is to that, And what makes this man lean, makes that man fat; What quenches one's thirst, makes another dry; And what makes this man wel, makes that man dye....

  • How do the environments in which businesses operate condition their success or failure? Such questions have long been of interest in the fields of business, economics and politics. They have gained in importance as a result of heightened competitive pressures associated with "globalization". While some see certain institutions as burdens, others see them as a blessing. This book thoroughly examines the main claims of the most important contribution--the Varieties of Capitalism paradigm--to this debate in recent years....
