Static Cosmological Solutions of Generalized Field Equations

Static Spherically Symmetric Solutions of SU(2) Einstein Yang Mills Equations with Positive Cosmological Constant

Static Axially Symmetric Solutions of Einstein-yang-mills Equations with a Negative Cosmological Constant: Black Hole Solutions

We investigate static axially symmetric black hole solutions in a four-dimensional Einstein-YangMills-SU(2) theory with a negative cosmological constant Λ. These solutions approach asymptotically the anti-de Sitter spacetime and possess a regular event horizon. A discussion of the main properties of the solutions and the differences with respect to the asymptotically flat case is presented. The...

General Relativistic Static Fluid Solutions with Cosmological Constant

Minimal generalized solutions of fuzzy polynomial equations

Fuzzy polynomial equations (FPEs) don’t have algebraic solutions, generally. In this paper, we first, express and prove some relationships between Husdroof meter and length function on classes of triangular fuzzy numbers. We appraise the behavior of fuzzy polynomials by using the length function properties. Next, we transform a FPE into a generalized fuzzy polynomial equation (GFPE) and introdu...

Solutions of Generalized Recursive Metric-Space Equations

It is well known that one can use an adaptation of the inverse-limit construction to solve recursive equations in the category of complete ultrametric spaces. We show that this construction generalizes to a large class of categories with metric-space structure on each set of morphisms: the exact nature of the objects is less important. In particular, the construction immediately applies to cate...
