IEI develops time-domain finite differencing methods.
Since the earth velocity is unvarying in time,
a ``basics only'' book such as this omits
this topic since you can, in principle,
accomplish the same goals in the -domain.
There are some applications, however,
that give rise to time-variable coefficients
in their partial differential equations.
Recursive dip filtering is one application.
Residual migration is another.
Some formulations of DMO are another.
