Vector bundles and the icosahedron

چکیده
Describing the equation of a plane curve C as the determinant of a matrix of linear forms is a classical problem. A related issue is expressing C as the Pfaffian of a skewsymmetric matrix of forms. When the curve is defined by a harmonic homogeneous polynomial (a solution to Laplace’s equation), then the action of the Lie algebra of the orthogonal group SO(3,C) provides a natural such expression, and with it, a natural semi-stable rank two vector bundle E on C. This paper concerns itself with these bundles, which have trivial determinant and H(C,E) = 0.

Differentiation along Multivector Fields
The Lie derivation of multivector fields along multivector fields has been introduced by Schouten (see cite{Sc, S}), and studdied for example in cite{M} and cite{I}. In the present paper we define the Lie derivation of differential forms along multivector fields, and we extend this concept to covariant derivation on tangent bundles and vector bundles, and find natural relations between them and...
متن کاملFirst-principles study of crystalline bundles of single-walled boron nanotubes with small diameter
First-principles calculations based on density functional theory are performed to study structural and electronic properties of crystalline bundles of (n, 0) zigzag and (0, n) armchair-type single-walled boron nanotubes (SWBNT) with small diameter, about 4–6 Å. The results predict a modification in the properties of SWBNT bundles relative to those of isolated nanotubes with small diameter. The ...
متن کاملON THE LIFTS OF SEMI-RIEMANNIAN METRICS
In this paper, we extend Sasaki metric for tangent bundle of a Riemannian manifold and Sasaki-Mok metric for the frame bundle of a Riemannian manifold [I] to the case of a semi-Riemannian vector bundle over a semi- Riemannian manifold. In fact, if E is a semi-Riemannian vector bundle over a semi-Riemannian manifold M, then by using an arbitrary (linear) connection on E, we can make E, as a...
متن کاملPublished vs. Postgraduate Writing in Applied Linguistics: The Case of Lexical Bundles
Abstract: Lexical bundles, as building blocks of coherent discourse, have been the subject of much research in the last two decades. While many of such studies have been mainly concerned with exploring variations in the use of these word sequences across different registers and disciplines, very few have addressed the use of some particular groups of lexical bundles within some gen...
متن کاملUsing it Bundles in Published and Unpublished Writings
Lexical bundles are known as important elements of coherent discourse that have been the subject of much research. While the previous research has been mainly concerned with exploring variations in the use of these word sequences across different registers and disciplines, very few studies have addressed the use of some particular groups of lexical bundles within some types of academic writing....
