Projective Varieties

This research project will investigate how combining systems of tessellation1 , modularity2 and seriality3 can be utilised with a specific method of paper staining to explore visual pathways within an artwork. A serial system4 of modular tessellation will be implemented, whereby different “sets” of oil-and-pigment soaked paper modules will be constructed and formed into various configurations.

In the article, we see that the birational maps of degree d of the projective space Pn k form a locally closed subvariety of the projective space P(Sdn11), denoted Crd(n). In this paper, we will construct the notion of extended degree of rational maps, then we obtain the functor crd(n) that represents the variety Crd(n).

A natural and simple question asked is: Does the Cremona group Cr(n) admit a structure that is of an algebraic group of infinite dimension. This is still an open question because we don’t know if the set Cr≤d(n) of birational maps of degree ≤ d admits a structure of the algebraic variety.

This triangle shawl is knit from the center back to the bottom edge. You can knit this shawl with variety of commercial yarns or handspun yarn since gauge is not critical in this project. Just make sure you have enough yarn to cast off and choose a needle 2-3 sizes larger than recommended for the yarn. Finished measurements Approximately 48” (122 cm) wide from wing to wing and 22” (56 cm) long from top of center back to bottom edge of the shawl.

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.

We show that every smooth toric variety (and many other algebraic spaces as well) can be realized as a moduli space for smooth, projective, polarized varieties. Some of these are not quasi-projective. This contradicts a recent paper (Quasi-projectivity of moduli spaces of polarized varieties, Ann. of Math. 159 (2004) 597–639.). A polarized variety is a pair (X, H) consisting of a smooth projective variety X and a linear equivalence class of ample divisors H on X. For simplicity, we look at the case when X is smooth, numerical and linear equivalence coincide for divisors on X, H is very...

I prove a formula expressing the descendent genus g Gromov-Witten invariants of a projective variety X in terms of genus 0 invariants of its symmetric product stack S g+1 (X). When X is a point, the latter are structure constants of the symmetric group, and we obtain a new way of calculating the GromovWitten invariants of a point. 1. Introduction Let X be a smooth projective variety. The genus 0 Gromov-Witten invariants of X satisfy relations which imply that they can be completely encoded in the structure of a Frobenius manifold on the cohomology H ∗ (X, C). ...

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...

We prove Maruyama’s conjecture on the boundedness of slope semistable sheaves on a projective variety defined over a noetherian ring. Our approach also gives a new proof of the boundedness for varieties defined over a characteristic zero field. This result implies that in mixed characteristic the moduli spaces of Gieseker semistable sheaves are projective schemes of finite type. The proof uses a new inequality bounding slopes of the restriction of a sheaf to a hypersurface in terms of its slope and the discriminant.

The aim of this paper is to show that the preservation of irreducibility of sections between a variety and hypersurface by specializations and almost all sections between a linear subspace of dimension h = n − d of Pn and a nondegenerate variety k of dimension d 0 consists of s points in uniform position. Introduction The lemma of Haaris [2] about a set in the uniform position has attracted much attention in algebraic geometry. That is a set of points of a projective space such that any two subsets of them with the same cardinality have the same...

Common carp is one of the most important cultured species in Vietnam. The goal of the carp breed program was creation of a common carp breed with stable genetic qualities such as fast growth, high survival rate and attractive appearance. In the first phase (1981-1985) the program focused on the assessment of the original carp varieties, which should be used as initial materials for selection.

The rapid growth of the fruit industry in the Mekong Delta area of Vietnam has seen the emergence of many problems, including a shortage of planting material, inadequate nursery and orchard management, lack of agribusiness and marketing skills. These problems could not be improved with existing level of government extenstion service. This activity will focus on the mango industry in Tien Giang and Tra Vinh provinces where good varieties of mango are produced.
