The Continuity Method to Deform Cone Angle

, 2014
The continuity method is used to deform the cone angle of a weak conical K\"ahler-Einstein metric with cone singularities along a smooth anti-canonical divisor on a smooth Fano manifold.

Unique geodesics for Thompson's metric [PDF]

, 2013
In this paper a geometric characterization of the unique geodesics in Thompson's metric spaces is presented. This characterization is used to prove a variety of other geometric results.

The Lorentz Group Using Conformal Geometric Algebra and Split Quaternions for Color Image Processing: Theory and Practice

IEEE Access, 2023
The processing of color images is of great interest, because the human perception of color is a very complex process, still not well understood. In this article, firstly the authors present an analysis of the well-known mathematical methods used to model

The Kahler Cone as Cosmic Censor

, 2003
M-theory effects prevent five-dimensional domain-wall and black-hole solutions from developing curvature singularities. While so far this analysis was performed for particular models, we now present a model-independent proof that these solutions do not ...

Coupled Fixed Point Theorems of Single-Valued Mapping for c-Distance in Cone Metric Spaces

Journal of Applied Mathematics, 2012
A new concept of the c-distance in cone metric space has been introduced recently in 2011. The aim of this paper is to extend and generalize some coupled fixed-point theorems on c-distance in cone metric space. Some examples are given.

Normed Ordered and 𝐸-Metric Spaces

International Journal of Mathematics and Mathematical Sciences, 2012
In 2007, Haung and Zhang introduced the notion of cone metric spaces. In this paper, we define an ordered space 𝐸, and we discuss some properties and examples. Also, normed ordered space is introduced.

Normal Cones and Thompson Metric

, 2013
The aim of this paper is to study the basic properties of the Thompson metric $d_T$ in the general case of a real linear space $X$ ordered by a cone $K$.

Coupled fixed point analysis in fuzzy cone metric spaces with an application to nonlinear integral equations

Advances in Difference Equations, 2020
In this paper, we introduce the concept of coupled type and cyclic coupled type fuzzy cone contraction mappings in fuzzy cone metric spaces. We establish some coupled fixed point results without the mixed monotone property, and also present some coupled ...

Fermions in a Global Monopole Background

, 1993
We study the scattering of fermions in a ``global monopole'' background metric. This is the four-dimensional analogue of the scattering on a cone in three dimensions. The scattering amplitude is exactly obtained.
