Positive radial solutions for the problem with Minkowski-curvature operator on an exterior domain

AIMS Mathematics, 2023
We are concerned with the problem with Minkowski-curvature operator on an exterior domain $ \begin{align} \left\{\begin{array}{ll} -\text{div}\Big(\frac{\nabla u}{\sqrt{1-|\nabla u|^2}}\Big) = \lambda K(|x|)\frac{f(u)}{u^\gamma}\ \ \ &\text{in ...

String and Fivebrane Solitons: Singular or Non-singular? [PDF]

, 1991
We ask whether the recently discovered superstring and superfivebrane solutions of D=10 supergravity admit the interpretation of non-singular solitons even though, in the absence of Yang-Mills fields, they exhibit curvature singularities at the origin ...

Removing singularities [PDF]

Journal of High Energy Physics, 2003
Big bang/crunch curvature singularities in exact CFT string backgrounds can be removed by turning on gauge fields. This is described within a family of {SL(2)xSU(2)xU(1)_x}/{U(1)xU(1)} quotient CFTs. Uncharged incoming wavefunctions from the ``whiskers'' of the extended universe can be fully reflected if and only if a big bang/crunch curvature ...

The balance in Gender in the Arabic language [PDF]

آداب الرافدين, 1987
A comparison between the isotopes and likenesses in the Arab tongue reveals to us a phenomenon indicating consistency and balance, which is lost in many issues scattered in separate Augusts that we can sum up in one chapter.

Singular Fermi Liquids [PDF]

, 2001
An introductory survey of the theoretical ideas and calculations and the experimental results which depart from Landau Fermi-liquids is presented. Common themes and possible routes to the singularities leading to the breakdown of Landau Fermi liquids are

Singular dimensions of the N=2 superconformal algebras. I [PDF]

, 1998
Verma modules of superconfomal algebras can have singular vector spaces with dimensions greater than 1. Following a method developed for the Virasoro algebra by Kent, we introduce the concept of adapted orderings on superconformal algebras.

Multiplicity of solutions of Kirchhoff-type fractional Laplacian problems with critical and singular nonlinearities

Electronic Journal of Qualitative Theory of Differential Equations, 2023
In this ariticle, the following Kirchhoff-type fractional Laplacian problem with singular and critical nonlinearities is studied: \begin{equation*} \begin{cases} \left(a+b\|u\|^{2\mu-2}\right)\left(-\Delta\right)^su=\lambda l(x)u^{2_{s}^{*}-1}+h(x)u ...

Singularity bifurcations [PDF]

Journal of Macroeconomics, 2006
equation models represent an important class of macroeconomic systems. Our ongoing research (He and Barnett (2003)) on the Leeper and Sims (1994) Euler equations macroeconometric model is revealing the existence of singularity-induced bifurcations, when the model¡¯s parameters are within a confidence region about the parameter estimates. Although known
