Solving the Initial Value Problem of two Black Holes [PDF]

, 2000
We solve the elliptic equations associated with the Hamiltonian and momentum constraints, corresponding to a system composed of two black holes with arbitrary linear and angular momentum.

The Initial Value Problem For Maximally Non-Local Actions [PDF]

, 1997
We study the initial value problem for actions which contain non-trivial functions of integrals of local functions of the dynamical variable. In contrast to many other non-local actions, the classical solution set of these systems is at most discretely ...

On a characteristic initial value problem in Plasma physics [PDF]

, 2005
The relativistic Vlasov-Maxwell system of plasma physics is considered with initial data on a past light cone. This characteristic initial value problem arises in a natural way as a mathematical framework to study the existence of solutions isolated from

Variational data assimilation for the initial-value dynamo problem [PDF]

, 2011
The secular variation of the geomagnetic field as observed at the Earth's surface results from the complex magnetohydrodynamics taking place in the fluid core of the Earth.

Fuzzy initial value problem [PDF]

Surveys in Mathematics and its Applications, 2015
In this paper, we present the fuzzy solution concept of the initial value problem. After introducing a metric between two fuzzy vectors, we prove that the system of fuzzy equations has unique solution under some condition.

On initial-value and self-similar solutions of the compressible Euler equations [PDF]

, 1996
We examine numerically the issue of convergence for initial-value solutions and similarity solutions of the compressible Euler equations in two dimensions in the presence of vortex sheets (slip lines).

A New Formulation of the Initial Value Problem for Nonlocal Theories [PDF]

, 2010
There are a number of reasons to entertain the possibility that locality is violated on microscopic scales, for example through the presence of an infinite series of higher derivatives in the fundamental equations of motion.

Numerical solution for fractional Bratu’s initial value problem

Open Physics, 2017
In this paper, a method for solving fractional Bratu’s initial value problem (FBIVP) is presented. The main idea behind this work is the use of the Bezier curve method (BCM). To show the efficiency of the developed method, numerical results are presented.
