Charles Hartshorne's global argument for God's existence : [PDF]

open access: yes, 1982
The idea of combining several arguments for theism--a cumulative case--is not original with Hartshorne. However, few philosophers have self-consciously employed this strategy.

Existence and non-existence of global solutions for nonlinear hyperbolic equations of higher order [PDF]

open access: yes, 1995
summary:The existence and uniqueness of classical global solution and blow up of non-global solution to the first boundary value problem and the second boundary value problem for the equation $$ u_{tt}-\alpha u_{xx}-\beta u_{xxtt}=\varphi (u_x)_x $$ are ...

Global Existence and Nonexistence in a System of Petrovsky

open access: yesJournal of Mathematical Analysis and Applications, 2002
The author considers the problem \[ \begin{cases} u_{tt}+\Delta^2u+au_t|u_t|^{m-2}=bu|u|^{p-2}, &x\in \Omega\;\text{ and } t>0,\\ u(x,t)=\partial_\nu u(x,t)=0, &x\in \partial\Omega\;\text{ and } t\geq 0,\\ u(x,0)=\phi(x), u_t(x,0)=\psi(x), &x\in\Omega,\end{cases}\tag{1} \] where \(\Omega\) is a bounded domain of \({\mathbb{R}}^n\) with smooth boundary \

The global existence problem in general relativity

open access: yes, 2000
We survey some known facts and open questions concerning the global properties of 3+1 dimensional space--times containing a compact Cauchy surface. We consider space--times with an $\ell$--dimensional Lie algebra of space--like Killing fields. For each $\

Existence of positive solutions for non local p-Laplacian thermistor problems on time scales

open access: yes, 2007
We make use of the Guo-Krasnoselskii fixed point theorem on cones to prove existence of positive solutions to a non local p-Laplacian boundary value problem on time scales arising in many applications. © 2007 Victoria University.

Global existence of solutions of differential inclusions

open access: yes, 1992
In this paper we consider sufficient conditions for global existence of solutions to a differential inclusion, dxdt ϵ F(t, x), assuming existence of local solutions to it by means of Lyapunov's second method. Our theorem includes as special cases S.

Existence of a Global Solution for a Viscoelastic System

open access: yesJournal of Mathematical Analysis and Applications, 1998
The author considers the Cauchy problem for the viscoelastic system \[ v_t- u_x= 0,\quad u_t- f(v)_x+ ku= u_{xx} \] without the restriction that the initial data approach constants at infinity. Existence of unique classical solution is proved, including a priori estimates.

A global investigation of solitary-wave solutions to a two-parameter model for water waves

open access: yes, 1996
The model equation (2r''''/15)-(br'')+(ar)+(3r^2/2)-((r')^2/2)+[rr']'=0 arises as the equation for solitary-wave solutions to a fifth-order long-wave equation for gravitycapillary water waves.

Global existence results for impulsive functional differential equations

open access: yes, 2006
In this paper, we investigate the existence of solutions of impulsive delay differential equation{x′(t)=f(t,xt),t⩾0,t≠τk,k∈N,Δx(t)=Ik(x(t)),t=τk,k∈N. New global existence theorems are established without assuming the global existence of solutions of the ...
