Lifting of linear vector fields to fiber product preserving vertical gauge bundles

J. Kurek, W. M. Mikulski (2005)

Colloquium Mathematicae

Similarity:

We classify all natural operators lifting linear vector fields on vector bundles to vector fields on vertical fiber product preserving gauge bundles over vector bundles. We explain this result for some known examples of such bundles.

Natural operators lifting functions to affinors on higher order cotangent bundles

W. M. Mikulski (2004)

Annales Polonici Mathematici

Similarity:

For natural numbers n ≥ 3 and r ≥ 1 all natural operators $A : T_{| ℳ f ₙ}^{(0, 0)} ⟿ T^{(1, 1)} T^{r *}$ transforming functions from n-manifolds into affinors (i.e. tensor fields of type (1,1)) on the r-cotangent bundle are classified.

Natural differential operators between some natural bundles

Włodzimierz M. Mikulski (1993)

Mathematica Bohemica

Similarity:

Let $F$ and $G$ be two natural bundles over $n$ -manifolds. We prove that if $F$ is of type (I) and $G$ is of type (II), then any natural differential operator of $F$ into $G$ is of order 0. We give examples of natural bundles of type (I) or of type (II). As an application of the main theorem we determine all natural differential operators between some natural bundles.

On cotangent bundles of some natural bundles

Kolář, Ivan

Similarity:

The author studies relations between the following two types of natural operators: 1. Natural operators transforming vector fields on manifolds into vector fields on a natural bundle $F$ ; 2. Natural operators transforming vector fields on manifolds into functions on the cotangent bundle of $F$ . It is deduced that under certain assumptions on $F$ , all natural operators of the second type can be constructed through those of the first one.

On oriented vector bundles over CW-complexes of dimension 6 and 7

Martin Čadek, Jiří Vanžura (1992)

Commentationes Mathematicae Universitatis Carolinae

Similarity:

Necessary and sufficient conditions for the existence of $n$ -dimensional oriented vector bundles ( $n = 3, 4, 5$ ) over CW-complexes of dimension $\leq 7$ with prescribed Stiefel-Whitney classes $w_{2} = 0$ , $w_{4}$ and Pontrjagin class $p_{1}$ are found. As a consequence some results on the span of 6 and 7-dimensional oriented vector bundles are given in terms of characteristic classes.

On Weil Bundles of the First Order

Adgam Yakhievich Sultanov (2016)

Acta Universitatis Palackianae Olomucensis. Facultas Rerum Naturalium. Mathematica

Similarity:

The descriptions of Weil bundles, lifts of functions and vector fields are given. Actions of the automorphisms group of the Whitney sum of algebras of dual numbers on a Weil bundle of the first order are defined.
