Black hole state dependence as a single parameter

open access: yesJournal of High Energy Physics, 2020
It has previously been proposed that the black hole interior of typical state large black holes in AdS can be described using state-dependent operators. We investigate the possibility that the interior can be described by explicit time dependence, which ...

Strict Contractive Conditions and Common Fixed Point Theorems in Cone Metric Spaces

open access: yesFixed Point Theory and Applications, 2009
A lot of authors have proved various common fixed-point results for pairs of self-mappings under strict contractive conditions in metric spaces. In the case of cone metric spaces, fixed point results are usually proved under assumption that the cone is ...

Assad-Kirk-Type Fixed Point Theorems for a Pair of Nonself Mappings on Cone Metric Spaces

open access: yesFixed Point Theory and Applications, 2009
New fixed point results for a pair of non-self mappings defined on a closed subset of a metrically convex cone metric space (which is not necessarily normal) are obtained.

Primal-Dual Interior-Point Methods for Self-Scaled Cones [PDF]

open access: yesSIAM Journal on Optimization, 1998
Summary: We continue the development of a theoretical foundation for efficient primal-dual interior-point algorithms for convex programming problems expressed in conic form, when the cone and its associated barrier are self-scaled [see \textit{Yu. E. Nesterov} and \textit{M. J. Todd}, Math. Oper. Res. 22, 1-42 (1997; Zbl 0871.90064)].

A Comparison of Normal Cone Conditions for Homotopy Methods for Solving Inequality Constrained Nonlinear Programming Problems

open access: yesAdvances in Mathematical Physics, 2020
Homotopy methods are powerful tools for solving nonlinear programming. Their global convergence can be generally established under conditions of the nonemptiness and boundness of the interior of the feasible set, the Positive Linear Independent ...

New complexity analysis of full Nesterov-Todd step infeasible interior point method for second-order cone optimization [PDF]

open access: yesYugoslav Journal of Operations Research, 2018
We present a full Nesterov-Todd (NT) step infeasible interior-point algorithm for second-order cone optimization based on a different way to calculate feasibility direction. In each iteration of the algorithm we use the largest possible barrier parameter

Characterization of Banach Lattices in Terms of Quasi-Interior Points

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2013
In terms of quasi-interior points, criteria that a Banach lattice has order continuous norm or is an -space with a unit are given. For example, if is Dedekind complete and has a weak order unit, then has order continuous norm if and only if the set of

Lower semi-continuous regularization of mappings in partially ordered by cone normed spaces

open access: yesVìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Modelûvannâ, 2009
The scheme of the lower semi-continuous regularization of mappings in normed spaces is proposed. We make no assumptions on the interior of the ordering cone.

The Relationship between Two Kinds of Generalized Convex Set-Valued Maps in Real Ordered Linear Spaces

open access: yesAbstract and Applied Analysis, 2013
A new notion of the ic-cone convexlike set-valued map characterized by the algebraic interior and the vector closure is introduced in real ordered linear spaces.
