result Expected symmetry is obtained through universal behavior and compatibility of operations.

We consider one possible definition of a diffeological connection on a diffeological vector pseudo-bundle. It is different from the one proposed in [7] and is in fact simpler, since it is obtained by a straightforward adaption of the standard definition of a connection as an operator on the space of all smooth sections…

Smooth actions of the multiplicative monoid (R,)(\mathbb{R},\cdot) of real numbers on manifolds lead to an alternative, and for some reasons simpler, definition of a vector bundle, a double vector bundle and related structures like a graded bundle [Grabowski and Rotkiewicz, J. Geom. Phys. 2011]. For these reasons it is n…

This paper introduces \infty- and nn-fold vector bundles as special functors from the \infty- and nn-cube categories to the category of smooth manifolds. We study the cores and "n-pullbacks" of nn-fold vector bundles and we prove that any nn-fold vector bundle admits a non-canonical isomorphism to a decomposed …

A subbundle of variable dimension inside the tangent bundle of a smooth manifold is called a smooth distribution if it is the pointwise span of a family of smooth vector fields. We prove that all such distributions are finitely generated, meaning that the family may be taken to be a finite collection. Further, we show …

We develop the theory of smooth principal bundles for a smooth group GG, using the framework of diffeological spaces. After giving new examples showing why arbitrary principal bundles cannot be classified, we define DD-numerable bundles, the smooth analogs of numerable bundles from topology, and prove that pulling ba…

We consider when a smooth vector bundle endowed with a connection possesses non-trivial, local parallel sections. This is accomplished by means of a derived flag of subsets of the bundle. The procedure is algebraic and rests upon the Frobenius Theorem.

The tangent bundle TkMT^kM of order kk, of a smooth Banach manifold MM consists of all equivalent classes of curves that agree up to their accelerations of order kk. For a Banach manifold MM and a natural number kk first we determine a smooth manifold structure on TkMT^kM which also offers a fiber bundle structure f…

method Defined a Hitchin map and spectral correspondence, stated Hitchin-Kobayashi correspondence.
result Established a theory halfway between curve and higher-dimensional variety Higgs bundles.

In this paper, we show that if the tangent bundle of a smooth projective variety is strictly nef, then it is isomorphic to a projective space; if a projective variety XnX^n (n>4)(n>4) has strictly nef Λ2TXΛ^2 TX, then it is isomorphic to Pn\mathbb{P}^n or quadric Qn\mathbb{Q}^n. We also prove that on elliptic curves, strict…

We study a smooth analogue of jumping curves of a holomorphic vector bundle, and use Yang-Mills theory over S2 S ^{2} to show that any non-trivial, smooth Hermitian vector bundle EE over a smooth simply connected manifold, must have such curves. This is used to give new examples complex manifolds for which a non-tri…

We prove that all smooth sphere bundles that admit fiberwise 1/4-pinched metrics are induced bundles of vector bundles, so their structure groups reduce from the diffeomorphism group of the sphere to the orthogonal group. This result implies the existence of many smooth n-sphere bundles over a k-sphere that do not supp…

result Lelong numbers of the associated forms are integers if singularities are integral.

First, we extend the notion of second order differential equations (SODE) on a smooth manifold to anchored Banach vector bundles. Then we define the Banach Lie algebroids as Lie algebroids structures modeled on anchored Banach vector bundles and prove that they form a category.

For each holomorphic vector bundle we construct a holomorphic bundle 2-gerbe that geometrically represents its second Beilinson-Chern class. Applied to the cotangent bundle, this may be regarded as a higher analogue of the canonical line bundle in complex geometry. Moreover, we exhibit the precise relationship between …

Let XX be a smooth projective variety over C\mathbb C. We prove that a twisted Higgs vector bundle $(\calE\, ,θ)$ on XX admits an Einstein--Hermitian connection if and only if $(\calE\, ,θ)$ is polystable. A similar result for twisted vector bundles (no Higgs fields) was proved by S. Wang in \cite{Wa}. Our approach …

We introduce several families of filtrations on the space of vector bundles over a smooth projective variety. These filtrations are defined using the large k asymptotics of the kernel of the Dolbeault Dirac operator on a bundle twisted by the kth power of an ample line bundle. The filtrations measure the failure of the…
