The extremal solution for the fractional Laplacian [PDF]

open access: yesCalculus of Variations and Partial Differential Equations, 2013
We study the extremal solution for the problem $(-Δ)^s u=λf(u)$ in $Ω$, $u\equiv0$ in $\R^n\setminusΩ$, where $λ>0$ is a parameter and $s\in(0,1)$. We extend some well known results for the extremal solution when the operator is the Laplacian to this nonlocal case.

Universal entropy and hawking radiation of near-extremal AdS4 black holes

open access: yesJournal of High Energy Physics, 2021
We compute the Bekenstein-Hawking entropy of near-extremal asymptotically AdS4 electrically charged rotating black holes using three different methods: (i) from the gravity solution, (ii) from the near-horizon Kerr/CFT correspondence and (iii) from the ...

Excited States of Maximal Warm Holes

open access: yesUniverse, 2023
Recently, the Einstein–Maxwell–scalar model with a non-minimal coupling between the scalar and Maxwell fields was explored. As a result, a new class of black hole solutions with scalar hair was discovered.

Constrained extremal solutions of multi-valued linear inclusions in Banach spaces

open access: yesJournal of Inequalities and Applications, 2016
Let X and Y be Banach spaces, L be a linear manifold in X × Y $X\times Y$ , or, equivalently, the graph of a multi-valued linear operator from X to Y, and let S be a prescribed hyperplane in X, i.e. S = g + N $S=g+N$ .

Uniqueness of near-horizon geometries of rotating extremal AdS(4) black holes [PDF]

open access: yes, 2009
We consider stationary extremal black hole solutions of the Einstein-Maxwell equations with a negative cosmological constant in four dimensions. We determine all non-static axisymmetric near-horizon geometries and all static near-horizon geometries for ...

On the Growth of Solutions of Second Order Linear Complex Differential Equations whose Coefficients Satisfy Certain Conditions

open access: yesمجلة بغداد للعلوم, 2020
In this paper, we study the growth of solutions of the second order linear complex differential equations  insuring that any nontrivial solutions are of infinite order.

Extremal connectedness of hedge funds [PDF]

open access: yes, 2022
peer reviewedWe propose a dynamic measure of extremal connectedness tailored to the short reporting period and unbalanced nature of hedge funds data. Using multivariate extreme value regression techniques, we estimate this measure conditional on factors ...
