Accelerating simulation of ensembles of locally differing optical structures via a Schur complement domain decomposition
Accelerating simulation optical structures Schur complement domain decomposition
2015/8/6
We present a Schur complement domain decomposition method that can significantly accelerate simulation of ensembles of locally differing optical structures. We apply the method to design a multi-spati...
Optical structures, algebraically special spacetimes, and the Goldberg-Sachs theorem in five dimensions
algebraically special spacetimes Goldberg-Sachs theorem
2010/12/20
Optical (or Robinson) structures are one generalisation of four-dimensional shearfree congruences of null geodesics to higher dimensions. They are Lorentzian analogues of complex and CR structures. In...
