Extremal Solutions of Functional Differential Inclusions

Journal of Mathematical Analysis and Applications, 1993
Let \(X\) be a separable Banach space; \({\mathcal K}\subset X\) be a cone and \(v: [-\tau,a]\to X\) be a solution of a problem \(\dot v(t)\in F(t,v_ t)+{\mathcal K}\), \(t\in [0,a]\); \(v_ 0\geq\varphi\), where \(F\) is a Carathéodory type multifunction with convex closed values satisfying the Ambrosetti type regularity condition. The viability result

Existence of extremal solutions for fuzzy polynomials and their numerical solutions

, 2007
In this paper, we consider the existence of a solution for fuzzy polynomials anx^n + an−1x^n−1 + · · · + a1x + a0 = x, where ai, i = 0, 1, 2, · · · , n and x are positive fuzzy numbers satisfying certain conditions. To this purpose, we use fixed point theory, applying results such as the well-known fixed point theorem of Tarski, presenting some results ...

Two kissing bolts

Journal of High Energy Physics, 2018
The study of non-supersymmetric black hole microstates offers the potential to resolve the black hole information paradox. A system of equations was recently obtained that enables the systematic construction of non-supersymmetric smooth horizonless ...

Non-BPS black branes in M-theory over Calabi-Yau threefolds. (Non-)uniqueness and recombination of non-BPS black strings in single modulus CICY and THCY models

Journal of High Energy Physics, 2022
We study extremal solutions arising in M-theory compactifications on Calabi-Yau threefolds, focussing on non-BPS attractors for their importance in relation to the Weak Gravity Conjecture (WGC); M2 branes wrapped on two-cycles give rise to black holes ...

Einstein-Maxwell-scalar black holes: classes of solutions, dyons and extremality

Journal of High Energy Physics, 2019
Spherical black hole (BH) solutions in Einstein-Maxwell-scalar (EMS) models wherein the scalar field is non-minimally coupled to the Maxwell invariant by some coupling function are discussed. We suggest a classification for these models into two classes,

On the extremal solutions of semilinear elliptic problems [PDF]

, 2004
We investigate here the properties of extremal solutions for semilinear elliptic equation −∆u = λ f (u) posed on a bounded smooth domain of Rn with Dirichlet boundary con-dition and with f exploding at a finite positive value a ...
