On the algebraic topology of weighted projective spaces
نویسنده
چکیده
From the viewpoint of algebraic topology, a quasitoric orbifold is a singular space that is constructed out of a simple polytope and a related integral matrix, and admits a well-behaved torus action. Weighted projective spaces P(χ) provide a particularly illuminating class of examples (where χ denotes a weight vector of natural numbers), but their topological literature is remarkably sparse. Our aim would be to introduce an audience of geometers to some of the more fundamental topological properties of P(χ), based on recent and ongoing work with Tony Bahri and Matthias Franz. We would expect to describe their integral cohomology rings, both ordinary and equivariant, in terms of piecewise polynomials, and to sketch relationships between P(χ) and the Borel construction, homotopy colimits, and iterated Thom complexes.

Bundles over Quantum RealWeighted Projective Spaces
The algebraic approach to bundles in non-commutative geometry and the definition of quantum real weighted projective spaces are reviewed. Principal U(1)-bundles over quantum real weighted projective spaces are constructed. As the spaces in question fall into two separate classes, the negative or odd class that generalises quantum real projective planes and the positive or even class that genera...
متن کاملAlgebraic Cocycles on Normal, Quasi-Projective Varieties
Blaine Lawson and the author introduced algebraic cocycles on complex algebraic varieties in [FL-1] and established a duality theorem relating spaces of algebraic cocycles and spaces of algebraic cycles in [FL-2]. This theorem has non-trivial (and perhaps surprising) applications in several contexts. In particular, duality enables computations of “algebraic mapping spaces” consisting of algebra...
متن کاملSome Results on TVS-cone Normed Spaces and Algebraic Cone Metric Spaces
In this paper we introduce the cone bounded linear mapping and demonstrate a proof to show that the cone norm is continuous. Among other things, we prove the open mapping theorem and the closed graph theorem in TVS-cone normed spaces. We also show that under some restrictions on the cone, two cone norms are equivalent if and only if the topologies induced by them are the same. In the sequel, we...
متن کاملAlgebraic and topological aspects of quasi-prime ideals
In this paper, we define the new notion of quasi-prime ideal which generalizes at once both prime ideal and primary ideal notions. Then a natural topology on the set of quasi-prime ideals of a ring is introduced which admits the Zariski topology as a subspace topology. The basic properties of the quasi-prime spectrum are studied and several interesting results are obtained. Specially, it is pro...
متن کاملWeighted Grassmannians
Many classes of projective algebraic varieties can be studied in terms of graded rings. Gorenstein graded rings in small codimension have been studied recently from an algebraic point of view, but the geometric meaning of the resulting structures is still relatively poorly understood. We discuss here the weighted projective analogs of homogeneous spaces such as the Grassmannian Gr(2, 5) and ort...
