Typical field lines of Beltrami flows and boundary field line behaviour of Beltrami flows on simply connected, compact, smooth manifolds with boundary
• Mathematics
Annals of Global Analysis and Geometry
• 2021
We characterise the boundary field line behaviour of Beltrami flows on compact, connected manifolds with vanishing first de Rham cohomology group. Namely we show that except for an at most nowhere
Topological Features Of Inviscid Flows
• Mathematics
• 2001
The Euler equations for an incompressible inviscid fluid in dimension three possess a wealth of topological phenomena woven into the dynamical and geometric properties of the fluid. Focusing first on
Bi-invariant metric on volume-preserving diffeomorphisms group of a three-dimensional manifold
We show the existence of a weak bi-invariant symmetric nondegenerate 2-form on the volume-preserving diffeomorphism group of a three-dimensional manifold and study its properties. Despite the fact
TOPOLOGICALLY MASSIVE ABELIAN GAUGE THEORY
We discuss three mathematical structures which arise in topologically massive Abelian gauge theory. First, the Euclidean topologically massive Abelian gauge theory defines a contact structure on a
Bi-invariant metric on contact diffeomorphisms group
We show the existence of a weak bi-invariant symmetric nondegenerate 2-form on the contact diffeomorphisms group $\mathcal{D}_\theta$ of a contact Riemannian manifold $(M,g,\theta)$ and study its
Identification of the Configuration Space Kähler Function
There are two basic approaches to quantum TGD. The first approach, which is discussed in this article, is a generalization of Einstein’s geometrization program of physics to an infinitedimensional
Physics as In nite-dimensional Geometry I : Identi cation of the Con guration Space Kähler Function
There are two basic approaches to quantum TGD. The rst approach, which is discussed in this article, is a generalization of Einstein's geometrization program of physics to an in nite-dimensional
Physics as Infinite-dimensional Geometry III: Configuration Space Spinor Structure
There are three separate approaches to the challenge of constructing WCW Kahler geometry and spinor structure. The first approach relies on a direct guess of Kahler function. Second approach relies

A contact structure £ on a 3-manifold M is called tight if the characteristic foliation of any embedded disc D has no limit cycle, and £ is called overtwisted if otherwise. The classification of over
