Vector fields on polyhedra [PDF]
Transactions of the American Mathematical Society, 1977 This paper presents a bundle theory for studying vector fields and their integral flows on polyhedra ∗ _ \ast and applications. Every polyhedron has a tangent object in the category of simplicial bundles in much the same way as every smooth manifold has a tangent object in the category of smooth vector bundles.

Selecciones MatemáticasIn this work, we study actions of the Lie group SL(2,C) on a complex manifold of dimension three or higher. It is demonstrated that these types of actions induce three complete holomorphic vector fields, one of which is periodic, and that there exists a

Vector fields satisfying the barycenter property
Open Mathematics, 2018 We show that if a vector field X has the C1 robustly barycenter property then it does not have singularities and it is Axiom A without cycles. Moreover, if a generic C1-vector field has the barycenter property then it does not have singularities and it ...

Vector fields in the presence of a contact structure
, 2005 We consider the Lie algebra of all vector fields on a contact manifold as a module over the Lie subalgebra of contact vector fields. This module is split into a direct sum of two submodules: the contact algebra itself and the space of tangent vector ...

Implicit quasilinear differential systems: a geometrical approach
Electronic Journal of Differential Equations, 1999 This work is devoted to the study of systems of implicit quasilinear differential equations. In general, no set of initial conditions is admissible for the system.

Projective Vector Fields on Semi-Riemannian Manifolds
MathematicsThis paper explores the properties of projective vector fields on semi-Riemannian manifolds. The main result establishes that if a projective vector field P on such a manifold is also a conformal vector field with potential function ψ and the vector ...

Primordial Magnetogenesis from Killing Vector Fields
UniversePapapetrou showed that the covariant derivative of a Killing vector field satisfies Maxwell’s equations in vacuum. Papapetrou’s result is extended, in this article, and it is shown that the covariant derivative of a Killing vector field satisfies Maxwell’

AdS S-matrix for massive vector fields
Journal of High Energy PhysicsWe generalize a recent “AdS S-matrix” formulation for interacting massive scalars on AdS spacetimes to the case of massive vector fields. This method relies on taking the infinite radius limit for scattering processes perturbatively, which is analyzed ...
