We begin this paper with a discussion of n-dimensional algebraic Vector bundles. Vector bundles of rank n may be identified with locally free Ox-modules of rank n. Several sections are dedicated to reviewing the basic notions of scheme-theory. We show how to construct the projectization of arbitrary rings. This construction corresponds to the construction of the tautological line bundle over an...

Let M be a simply connected Riemannian symmetric space, with at most one flat direction. We show that every Riemannian (or unitary) vector bundle with parallel curvature over M is an associated vector bundle of a canonical principal bundle, with the connection inherited from the principal bundle. The problem of finding Riemannian (or unitary) vector bundles with parallel curvature then reduces ...

The Hilbert scheme of n points in the projective plane parameterizes degree n zerodimensional subschemes of the projective plane. We examine the dual cones of effective divisors and moving curves on the Hilbert scheme. By studying interpolation, restriction, and stability properties of certain vector bundles on the plane we fully determine these cones for just over three fourths of all values o...

Let P be a parabolic subgroup of a semisimple complex Lie group G defined by a subset Σ of simple roots of G, and let Eφ be a homogeneous vector bundle over the flag manifold G/P corresponding to a linear representation φ of P . Using Bott’s theorem, we obtain sufficient conditions on φ in terms of the combinatorial structure of Σ for some cohomology groups of the sheaf of holomorphic sections ...

For a regular scheme and prime number $p$, we define the FW-cotangent bundle as vector on closed subscheme defined by $p=0$, under certain finiteness condition. constructible complex etale site of scheme, introduce condition to be micro-supported conical subset in bundle. At end article, compute singular supports some cases.

We deal with finite dimensional differentiable manifolds. All items are concerned with are differentiable as well. The class of differentiability is C∞. A metric structure in a vector bundle E is a constant rank symmetric bilinear vector bundle homomorphism of E × E in the trivial bundle line bundle. We address the question whether a given gauge structure in E is metric. That is the main concer...
