Finite-difference modeling of 2-D wave propagation in the vicinity of dipping interfaces: a comparison of anti-aliasing and equivalent medium approaches
Erik F. M. Koene, Jens Wittsten, Johan O. A. Robertsson
Finite-difference (FD) modeling of seismic waves in the vicinity of dipping interfaces gives rise to artifacts. Examples are phase and amplitude errors, as well as staircase diffra…

Quenched limit theorems for random U(1) extensions of expanding maps
Yong Moo Chung, Yushi Nakano, Jens Wittsten
The Lyapunov spectra of random U(1) extensions of expanding maps on the torus were investigated in our previous work [NW2015]. Using the result, we extend the recent spectral appro…
