Existence and uniqueness of Bowen–York trumpets [PDF]

open access: yesClassical and Quantum Gravity, 2011
We prove the existence of initial data sets which possess an asymptotically flat and an asymptotically cylindrical end. Such geometries are known as trumpets in the community of numerical relativists.

Existence and uniqueness theorems on certain difference-differential equations

open access: yesElectronic Journal of Differential Equations, 2009
In the present paper, existence and uniqueness theorems for the solutions of certain nonlinear difference-differential equations are established. The main tools employed in the analysis are based on the applications of the Leray-Schauder alternative ...

On the groundstate of octonionic matrix models in a ball

open access: yesPhysics Letters B, 2015
In this work we examine the existence and uniqueness of the groundstate of a SU(N)×G2 octonionic matrix model on a bounded domain of RN. The existence and uniqueness argument of the groundstate wavefunction follows from the Lax–Milgram theorem ...
