• #### An adaptive multiscale algorithm for efficient extended waveform inversion ﻿

(2017)
Subsurface-offset extended full-waveform inversion (FWI) may converge to kinematically accurate velocity models without the low-frequency data accuracy required for standard data-domain FWI. However, this robust alternative ...
• #### Migration velocity analysis and waveform inversion with subsurface offset extension ﻿

(2016-12-01)
Image-domain seismic inversion with subsurface offset extension may converge to kinematically accurate velocity models without the low-frequency data accuracy required for standard data-domain full waveform inversion. ...
• #### On the boundaries of special Lagrangian submanifolds ﻿

(1995)
An n-dimensional submanifold M in ${\bf C}\sp{n} = {\bf R}\sp{2n}$ is called Lagrangian if the restriction of $\omega$ to M is zero, where $\omega = \Sigma{\limits\sb{i}}dz\sb{i}\ \wedge\ d\bar z\sb{i}$. It is called special ...
