Tight Beltrami fields with symmetry.
Tight Beltrami fields with symmetry. Abstract Given a Seifered fibred 3-manifold M equipped with an S 1-invariant contact form α, we provide a bound on the volume Vol(M) and the curvature, in a suitable adapted Riemannian metric to α, which implies universal tightness of the contact structure ξ = ker α.
متن کاملComputing Beltrami Fields
Abstract. For solving the non-linear equations governing force-free fields, an iterative methodology based on the splitting of the problem is described. On the basis of this splitting, three families of subproblems have to be solved numerically. The first problem consists to find a potential field. A mixed hybrid method is used to solve it. The second problem, which is a curl-div system, is sol...
متن کاملThe Laplace-Beltrami operator on surfaces with axial symmetry
The physical situation which has initiated this research is that of a dielectric particle with electric charges on its surface, placed in electric field. Here, the diffusion equation of the charges is coupled with the Maxwell equations. There is an analytical solution of this system of equation [1] which involves some functional calculus with operators, in particular with Laplace-Beltrami opera...
متن کاملOn Beltrami fields with nonconstant proportionality factor on the plane
We consider the equation rot −→ B + α −→ B = 0 (1) in the plane with α being a real-valued function and show that it can be reduced to a Vekua equation of a special form. In the case when α depends on one Cartesian variable a complete system of exact solutions of the Vekua equation and hence of equation (1) is constructed based on L. Bers’ theory of formal powers.
متن کاملTight focusing of spatially variant vector optical fields with elliptical symmetry of linear polarization.
We study the tight-focusing properties of spatially variant vector optical fields with elliptical symmetry of linear polarization. We found the eccentricity of the incident polarized light to be an important parameter providing an additional degree of freedom assisting in controlling the field properties at the focus and allowing matching of the field distribution at the focus to the specific a...
