On parameters of the Levi-Civita solution
نویسنده
چکیده
The Levi-Civita (LC) solution is matched to a cylindrical shell of an anisotropic uid. The uid satis es the energy conditions when the mass parameter is in the range 0 1. The mass per unit length of the shell is given explicitly in terms of , which has a nite maximum. The relevance of the results to the non-existence of horizons in the LC solution and to gauge cosmic strings is pointed out. PACS numbers: 04.20.Jb, 04.20.Cv, 98.80.Cq, 97.60.Lf

Operator-valued tensors on manifolds
In this paper we try to extend geometric concepts in the context of operator valued tensors. To this end, we aim to replace the field of scalars $ mathbb{R} $ by self-adjoint elements of a commutative $ C^star $-algebra, and reach an appropriate generalization of geometrical concepts on manifolds. First, we put forward the concept of operator-valued tensors and extend semi-Riemannian...
متن کاملEnergy-Momentum Distribution of the Weyl-Lewis-Papapetrou and the Levi-Civita Metrics
This paper is devoted to compute the energy-momentum densities for two exact solutions of the Einstein field equations by using the prescriptions of Einstein, Landau-Lifshitz, Papapetrou and Möller. The spacetimes under consideration are the Weyl-Lewis-Papapetrou and the Levi-Civita metrics. The Weyl metric becomes the special case of the Weyl-Lewis-Papapetrou solution. The Levi-Civita metric p...
متن کاملAffine Invariant Measures in Levi-Civita Vector Spaces and the Erdös Obtuse Angle Theorem
An interesting question posed by Paul Erdös around 1950 pertains to the maximal number of points in n-dimensional Euclidean Space so that no subset of three points can be picked that form an obtuse angle. An unexpected and surprising solution was presented around a decade later. Interestingly enough the solution relies in its core on properties of measures in n-dimensional space. Beyond its int...
متن کاملOn the Existence and Uniqueness of Solutions of Ordinary Differential Equations on the Levi-civita Field
The solution of an ordinary differential equation with constant coefficients on the Levi-Civita field is investigated. Contrary to the real case, we first show that even when the order of the equation is finite, it has infinitely many linearly independent solutions; moreover, any corresponding initial value problem has infinitely many solutions. The problems mentioned above are due to the disco...
متن کاملLevi-Civita spacetimes in multidimensional theories
We obtain the most general static cylindrically symmetric vacuum solutions of the Einstein field equations in (4+N) dimensions. Under the assumption of separation of variables, we construct a family of Levi-Civita-Kasner vacuum solutions in (4 + N). We discuss the dimensional reduction of the static solutions. Depending on the reduction procedure, they can be interpreted either as a scalar-vacu...
