Supergravities with Minkowski x Sphere Vacua [PDF]

, 2004
Recently the authors have introduced a new gauged supergravity theory with a positive definite potential in D=6, obtained through a generalised Kaluza-Klein reduction from D=7.

On Positive Solutions of the Heat Equation [PDF]

Nagoya Mathematical Journal, 1967
Consider the positive and twice continuously differentiable solutions u of the heat equationin an open t-strip Ω = Rn×(0,T) for some T>0, where Rn is the n-dimensional Euclidean space.In this note, we prove a theorem of Fatou type on u and, as its application, the uniqueness theorem for the Cauchy problem of ( 1 ).

On Positive Solutions for Some Nonlinear Semipositone Elliptic Boundary Value

Nonlinear Analysis, 2006
This study concerns the existence of positive solutions to classes of boundary value problems of the form −∆u = g(x,u), x ∈ Ω, u(x) = 0, x ∈ ∂Ω, where ∆ denote the Laplacian operator, Ω is a smooth bounded domain in RN (N ≥ 2) with ∂Ω of class C2, and ...

Unique positive solution for an alternative discrete Painlevé I equation [PDF]

, 2015
We show that the alternative discrete Painlevé I equation (alt-) has a unique solution which remains positive for all . Furthermore, we identify this positive solution in terms of a special solution of the second Painlevé equation () involving the Airy ...

Equilibrium solution to the lowest unique positive integer game

, 2010
We address the equilibrium concept of a reverse auction game so that no one can enhance the individual payoff by a unilateral change when all the others follow a certain strategy.

Positive solution for a fractional singular boundary value problem with p-Laplacian operator

, 2018
In this paper, we consider a fractional singular three-point boundary value problem with p-Laplacian operator. The nonlinearity f(t,u)$f(t,u)$ may be singular at t=0,1$t = 0,1$ and u=0$u = 0$. Some properties of the associated Green function are obtained.
