A boundary value problem for the wave equation

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1999
Traditionally, boundary value problems have been studied for elliptic differential equations. The mathematical systems described in these cases turn out to be “well posed”. However, it is also important, both mathematically and physically, to investigate

Calculation of free fall trajectories based on numerical optimization techniques [PDF]

open access: yes
The development of a means of computing free-fall (nonthrusting) trajectories from one specified point in the solar system to another specified point in the solar system in a given amount of time was studied.

A Boundary Value Problem for Hermitian Monogenic Functions

open access: yesBoundary Value Problems, 2008
We study the problem of finding a Hermitian monogenic function with a given jump on a given hypersurface in ℝm, m=2n. Necessary and sufficient conditions for the solvability of this problem are obtained.
